电力英语单词

电力英语单词Electricity英语单词包括:1. Electricity2. Power3. Voltage4. Current5. Circuit6. Generator7. Transformer8. Conductor9. Insulator10. SwitchElectricity is the flow of electric power or charge. It is a form of energy that comes from the movement of electrons. When these electrons are in motion, they create an electric current. This current can be harnessed to power various devices and systems.Electricity is measured in units of voltage, current, and resistance. Voltage is the force that pushes the electric charge through a circuit, while current is the rate of flow of electric charge. Resistance is the opposition to the flow of electric charge.A circuit is a closed loop through which an electric current can flow. It consists of a source of electrical energy, such as a battery or generator, and various components such as wires, switches, and resistors.Generators are devices that convert mechanical energy into electrical energy. They work on the principle of electromagnetic induction, where a conductor moving through a magnetic field generates an electric current.Transformers are devices used to change the voltage of an electric current. They are essential for transmitting electricity over long distances and for stepping up or stepping down the voltage as needed.Conductors are materials that allow electric current to flow through them easily, while insulators are materials that do not allow electric current to pass through them.This property of materials is crucial in designingelectrical systems and devices.Switches are devices used to control the flow ofelectric current in a circuit. They can open or close the circuit, thus controlling the flow of electricity tovarious components.电力是电力或电荷的流动。

UNIT1A电路1.电路或电网络由以某种方式连接的电阻器、电感器和电容器等元件组成。

如果网络不包含能源如电池或发电机,那么就被称作无源网络。

换句话说,如果存在一个或多个能源,那么组合的结果为有源网络。

在研究电网络的特性时,我们感兴趣的是确定电路中的电压和电流。

因为网络由无源电路元件组成,所以必须首先定义这些元件的电特性2.就电阻来说,电压电流的关系由欧姆定律给出,欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值。

在数学上表达为:U=R(1-1A-)式中U=电压,伏特;i=流,安培;R=电阻欧姆3.纯电感电压由法拉第定律定义,法拉第定律指岀电感两端的电压正比于流过电感的电流随时间的变化率。

因此可得到:Uddt式中didt=电流变化率,安培/秒;L=感应系数,享利。

4.电容两端建立的电压正比于电容两极板上积累的电荷q。

因为电荷的积累可表示为电荷增量dq的和或积分,因此得到的等式为U=,式中电量C是与电压和电荷相关的比例常数。

由定义知,电流等于电荷随时间的变化率,可表示为dadt。

因此电荷增量da等于电流乘以相应的间增量,或dq=idt,那么等式(1A3)可写为中C=电容量,法拉。

5.归纳式(1-A1)、(1-1A2)和(1-A4)描述的三无源电路元件如图1A-所示。

注意,图中的参考方向为惯用的参考方向,因此流过元件的电流与电压降的方向一致6.有源电气元件涉及将其它能量转换为电能,例如,电池中的电能来自其储存的化学能,发电机的能是旋转电枢机械能转换的结果。

7.有源电气元件存在两种基本形式:电压源和电源。

其理想状态为:电压源两端的电压恒定,与从电压源中流出的电流无关。

因为负载变化时电压基本恒定,所以上述电池和发电机被认为是电压源。

另一方面,电流源产生电流,电流的大小与电源连接的负载无关。

虽然电流源在实际中不常见,但其概念的确在表示借助于等值电路的放大器件,比如晶体管中具有广泛应用。

电压源和电流源的符号表示如图1A2所示8.分析电网络的一般方法是网孔分析法或回路分析法。

Photoelectric sensorKey word: photoelectric effect photoelectric element photoelectric sensor classification sensor application characteristics .Abstract: in the rapid development of science and technology in the modern society, mankind has into the rapidly changing information era, people in daily life, the production process, rely mainly on the detection of information technology by acquiring, screening and transmission, to achieve the brake control, automatic adjustment, at present our country has put detection techniques listed in one of the priority to the development of science and technology. Because of microelectronics technology, photoelectric semiconductor technology, optical fiber technology and grating technical development makes the application of the photoelectric sensor is growing. The sensor has simple structure, non-contact, high reliability, high precision, measurable parameters and quick response and more simple structure, form etc, and flexible in automatic detection technology, it has been widely applied in photoelectric effect as the theoretical basis, the device by photoelectric material composition. Text:First, theoretical foundation - photoelectric effectPhotoelectric effect generally have the photoelectric effect, optical effect, light born volts effect.The light shines in photoelectric material, according to the electronic absorption material surface energy, if absorbed energy large enough electronic electronic will overcome bound from material surface and enter the outside space, which changes photoelectron materials, this kind of phenomenon become the conductivity of the photoelectric effectAccording to Einstein's photoelectron effect, photon is moving particles, each photon energy for hv (v for light frequency, h for Planck's constant, h = 6.63 * 10-34 J/HZ), thus different frequency of photons have different energy, light, the higher the frequency, the photon energy is bigger. Assuming all the energy photons to photons, electronic energy will increase, increased energy part of the fetter, positive ions used to overcome another part of converted into electronic energy. According to the law of conservation of energy:Type, m for electronic quality, v for electronic escaping the velocity, A microelectronics the work done.From the type that will make the optoelectronic cathode surface escape the necessary conditions are h > A. Due to the different materials have different escaping, so reactive to each kind of cathode materials, incident light has a certain frequency is restricted, when the frequency of incident light under this frequency limit, no matter how the light intensity, won't produce photoelectron launch, this frequency limitA -h m 212νν=called "red limit". The corresponding wavelength for type, c for the speed of light, A reactive for escaping.When is the sun, its electronic energy, absorb the resistivity reduce conductive phenomenon called optical effects. It belongs to the photoelectric effect within. When light is, if in semiconductor electronic energy big with semiconductor of forbidden band width, the electronic energy from the valence band jump into the conduction band, form, and at the same time, the valence band electronic left the corresponding cavities. Electronics, cavitation remained in semiconductor, and participate in electric conductive outside formed under the current role.In addition to metal outer, most insulators and semiconductor have photoelectric effect, particularly remarkable, semiconductor optical effect according to the optoelectronics manufacturing incident light inherent frequency, when light resistance in light, its conductivity increases, resistance drops. The light intensity is strong, its value, if the smaller, its resistance to stop light back to the original value. Semiconductor produced by light illuminate the phenomenon is called light emf, born volts effect on the effect of photoelectric devices have made si-based ones, photoelectric diode, control thyristor and optical couplers, etc.Second, optoelectronic components and characteristicsAccording to the outside optoelectronics manufacturing optoelectronic devices have photoelectron, inflatable phototubes and photoelectric times once tube.1. Phototubes phototubes are various and typical products are vacuum phototubes and inflatable phototubes, light its appearance and structure as shown in figure 1 shows, made of cylindrical metal half cathodic K and is located in the wires cathodic axis of anode in A package of smoke into the vacuum, when incident light within glass shell in the cathode, illuminate A single photon took all of its energy transfer to the cathode materials A free electrons, so as to make the freedom electronic energy increase h. When electrons gain energy more than escape of cathode materials, it reactive A metal surface constraints can overcome escape, form electron emission. This kind of electronic called optoelectronics, optoelectronic escaping the metal surface for after initial kinetic energyPhototubes normal work, anode potential than the cathode, shown in figure 2. In one shot more than "red light frequency is premise, escape from the optoelectronic cathode surface by positive potential attracted the anode in photoelectric tube forming space, called the current stream. Then if light intensity increases, the number of photons bombarded the cathode multiplied, unit of time to launch photoelectron number are also increasing, photo-current greatens. In figure 2 shows circuit, current and resistance is the voltage drop across the only a function of light intensity relations, so as to achieve a photoelectric conversion. When the LTT optoelectronic cathode K, electronic escape from the cathode surface, and was the photoelectric anode is an electric current, power plants absorb deoxidization device in the load resistance - I, the voltagePhototubes photoelectric characteristics fig.03 shows, from the graph in flux knowable, not too big, photoelectric basic characteristics is a straight line.2. Photoelectric times had the sensitivity of vacuum tube due to low, so with people developed has magnified the photomultiplier tubes photo-current ability. Figure 4 is photomultiplier tube structure schematic drawing.图4光电倍增结构示意图From the graph can see photomultiplier tubes also have A cathode K and an anode A, and phototubes different is in its between anode and cathode set up several secondary emission electrodes, D1, D2 and D3... They called the first multiply electrode, the second multiply electrode,... Usually, double electrode for 10 ~ 15 levels. Photomultiplier tubes work between adjacent electrode, keeping a certain minimum, including the cathode potential potentials, each multiply electrode potential filtering increases, the anode potential supreme. When the incident light irradiation, cathodic K escape from the optoelectronic cathode multiplied by first accelerated, by high speed electrode D1 bombarded caused secondary electron emission, D1, an incident can generate multiple secondary electron photonics, D1 emit of secondary electron wasD1, D2 asked electric field acceleration, converged on D2 and again produce secondary electron emission... So gradually produce secondary electron emission, make electronic increased rapidly, these electronic finally arrived at the anode, form a larger anode current. If a n level, multiply electrodes at all levels for sigma, the multiplication of rate is the multiplication of photomultiplier tubes can be considered sigma n rate, therefore, photomultiplier tube has high sensitivity. In the output current is less than 1mA circumstances, it in a very wide photoelectric properties within the scope of the linear relationship with good. Photomultiplier tubes this characteristic, make it more for light measurement.3 and photoconductive resistance photoconductive resistance within the working principle is based on the photoelectric effect. In semiconductor photosensitive material ends of mount electrode lead, it contains transparent window sealed in the tube and shell element photoconductive resistance. Photoconductive resistance properties and parameters are:1) dark resistance photoconductive resistance at room temperature, total dark conditions stable resistance called dark resistance, at the current flow resistance is called dark current.2) light resistance photoconductive resistance at room temperature and certain lighting conditions stable resistance measured, right now is called light resistance of current flow resistance is called light current.4, volt-ampere characteristics of both ends photoconductive resistance added voltage and current flows through photoconductive resistance of the relationship between called volt-ampere characteristics shown, as shown in figure 5. From the graph, the approximate linear volt-ampere characteristics that use should be limited, but when the voltage ends photoconductive resistance, lest than shown dotted lines of power consumption area5, photoelectric characteristics photoconductive resistance between the poles, light when voltage fixed the relationship between with bright current photoelectric characteristics. Called Photoconductive resistance photoelectric characteristics is nonlinear, this is one of the major drawback of photoconductive resistance.6, spectral characteristics is not the same incident wavelength, the sensitivity of photoconductive resistance is different also. Incidence wavelength and photodetector the relationship between relative sensitivity called spectral characteristics. When used according to the wavelength range by metering, choose different material photoconductive resistance.7, response time by photoconductive resistance after photo-current need light, over a period of time (time) rise to reach its steady value. Similarly, in stop lightphoto-current also need, over a period of time (down time) to restore the its dark current, this is photoconductive resistance delay characteristics. Photoconductive resistance rise response time and falling response time about 10-1 ~ 10-3s, namely the frequency response is 10Hz ~ 1000Hz, visible photoconductive resistance cannot be used in demand quick response occasion, this is one of the main photoconductive resistance shortcomings.8 and temperature characteristic photoconductive resistance by temperature affects greatly, temperature rise, dark current increase, reduced sensitivity, which is another photoconductive resistance shortcomings.9, frequency characteristic frequency characteristics refers to an external voltage and incident light, strong must be photo-current I and incident light modulation frequency, the relationship between the f, photoelectric diode is the frequency characteristic of the photoelectric triode frequency characteristics, this is because of the photoelectrictriode shot "yankees there capacitance and carrier base-combed need time's sake. By using the principle of the photoelectric efficiency of optoelectronics manufacturing frequency characteristics of the worst, this is due to capture charge carriers and release charge need a certain time's sake.Three, photoelectric sensorsPhotoelectric sensor is through the light intensity changes into electrical signal changes to achieve control, its basic structure, it first figure 6 by measuring the change of change of converting the light signal, and then using photoelectric element further will light signals into electrical signal by photoelectric sensor general. Illuminant, optical path and optoelectronics. Three components of photoelectric detection method has high precision, fast response, non-contact wait for an advantage, but measurable parameters of simple structure, sensors, form flexible, therefore, photoelectric sensor in the test and control is widely used.By photoelectric sensor generally is composed of three parts, they are divided into: transmitter and receiver and detection circuit shown, as shown in figure 7, transmitter aimed at the target launch beam, the launch of the beam from semiconductor illuminant, general light emitting diode (LED), laser diode and infrared emission diode. Beam uninterrupted launch, or change the pulse width. Receivers have photoelectric diode, photoelectric triode, composed si-based ones. In front of the receiver, equipped with optical components such as lens and aperture, etc. In its back is detection circuit, it can filter out effective signal and the application of the signal. In addition, the structural components in photoelectric switch and launch plate and optical fiber, triangle reflex plate is solid structure launch device. It consists of small triangle cone of reflective materials, can make a beam accurately reflected back from plate, with practical significance. It can be in with the scope of optical axis 0 to 25, make beams change launch Angle from a root almost after launch line, passes reflection or from the rotating polygon.some basic returns.图7Photoelectric sensor is a kind of depend on is analyte and optoelectronics and light source, to achieve the relationship between the measured purpose, so the light source photoelectric sensor plays a very important role, photoelectric sensor power if a constant source, power is very important for design, the stability of the stability of power directly affect the accuracy of measurement, commonly used illuminant have the following kinds:1, leds is a change electric energy into light energy semiconductor devices. It has small volume, low power consumption, long life, fast response, the advantages of high mechanical strength, and can match and integrated circuits. Therefore, widely used in computer, instruments and automatic control equipment.2, silk light bulb that is one of the most commonly used illuminant, it has rich infrared light. If chosen optoelectronics, constitutes of infrared sensor sensitive colour filter can be added to the visible tungsten lamps, but only filter with its infrared does illuminant, such, which can effectively prevent other light interference.3, compared with ordinary light laser laser with energy concentration, directional good, frequency pure, coherence as well as good, is very ideal light sources.The light source, optical path and photoelectric device composition photoelectric sensor used in photoelectric detection, still must be equipped with appropriate measurement circuit. The photoelectric effect to the measurement circuit of photoelectric element of widerange caused changes needed to convert the voltage or current. Different photoelectric element, the measurement circuit required is not identical also. Several semiconductor introduces below optoelectronic devices commonly used measurement circuit.Semiconductor photoconductive resistance can through large current, be in so usually, need not equipped with amplifier. In the output power of demand is bigger, can use figure 8 shows circuit.Figure 9 (a) with temperature compensation given the photosensitive diode bridge type measuring circuit. When the incident light intensity slow change, the reverse resistance photosensitive diode is the slow change, the change of the temperature will cause the bridge output voltage, must compensate. Drift Picture a photosensitive diode as the test components, another into Windows, in neighboring bridge, the change of the temperature in the arms of the influence of two photosensitive diode, therefore, can eliminate the same output with temperature bridge road drift.Light activated triode incident light in work under low illumination, or hope to getbigger output power, also can match with amplifying circuit, as shown in figure 9 shows.Because even in the glare photosensitive batteries, maximum output voltage also only 0.6 V, still cannot make the next level 1 transistor have larger current output, so must add positive bias, as shown in figure 9 (a) below. In order to reduce the transistor circuit impedance variations, base si-based ones to reduce as much as possible without light, when the reverse bias inherit in parallel a resistor si-based ones at both ends. Or like figure 9 (b) as shown by the positive ge diode produces pressure drop and test the voltage produced when exposed to light, make silicon tube e stack, b the voltage between actuators than 0.7 V, and conduction work. This kind of circumstance also can use silicon light batteries, as shown in figure 10 (c) below. Semiconductor photoelectric element of photoelectric circuit can also use integrated operational amplifier. Silicon photosensitive diode can be obtained by integratingop-amp larger output amplitude, as shown in figure 11 (a) below. When light is produced, the optical output voltage in order to guarantee photosensitive diode isreverse biased, in its positive to add a load voltage. Figure 11. (b) give the photocell transform circuit, because the photoelectric si-based ones short-circuit current and illumination of a linear relationship between, so will it up in the op-amp is,inverse-phase input, using these two potential difference between the characteristicsof close to zero, can get better effect. In the picture shows conditions, the output voltageThe photoelectric element by flux the role of different made from the principle of optical measurement and control system is varied, press the photoelectric element (optical measurement and control system) output nature, namely, can be divided into second analog photoelectric sensor and pulse (switch) photoelectric sensor. Analog photoelectric sensors will be converted into continuous variation of the measure, it is measured optical with a single value relations between analog photoelectric sensor. According to be measured (objects) method detection of target can be divided into transmission (absorption) type, diffuse type, shading type (beam resistance gears) three categories. So-called transmission style means the object to be tested in optical path in constant light source, the light energy through things, part of being measured by absorption, transmitted light onto photoelectric element, such as measured liquid, gas transparency and photoelectric BiSeJi etc; speed.gratifying The so-called diffuse style means the constant light by the light onto the analyte from the object to be tested, and projected onto surfaces reflect on after optoelectronic devices, such as photoelectric colorimetric thermometer and light gauge etc; The so-called shading style means the when illuminant issued by the flux of light analyte covered by a part Jing optoelectronics, make projection on the flux change, change the object to be tested and extent of the position with the light path, such as vibration measurement, the size measurement; And in pulse photoelectric sensor in the sensors, photoelectric element acceptable optical signal is intermittent change, therefore photoelectric element in switch work of the state, the current output it is usually only two steady state of the signal, the pulse form used for photoelectric counting and photoelectric speed measurement and so on.And infrared photoelectric sensor classification and working way generally have thefollowing kinds:1, groove photoelectric sensor put a light emitter and a receiver in a slot face-to-face outfit are on opposite sides of the photoelectric groove. Lighter emits infrared light or visible light, and in unimpeded cases light receptors can receive light. But when tested objects from slot zhongtong obsolete, light occluded, photoelectric switches and action. Output a switch control signal, cut off or connect load current, thus completing a control movement. Groove switch is the overall of detection distance because general structure limits only a few centimeters.2, DuiShe type optoelectronic sensor if you put lighter and receive light is separated, can make the detection distance increase. By a lighter and an inbox light sensor into a photoelectric switch is called DuiShe separate photoelectric switches, referred to DuiShe photoelectric switch. Its detection distance can reach a few meters and even a dozen meters. When using light-emitting device and receive light device are installed in test object through the path of the sides, test object by blocking light path, accept light implement action output a switch control signals.3, reflex plate.it photoelectric switch light-emitting device type and receive light device into the same device inside, in its front pack a reflex plate.the using the reflection principle of complete photoelectric control function is called reflex plate.it reflex (or reflector reflex) photoelectric switch. Under normal circumstances, lighter the light reflected by reflex plate.it is received by accept light; Once the light path be test object to block, accept light, the light is not receive photoelectric switch is action, output a switch control signals.4, diffusion reflective photoelectric switches its detection head with a lighter and also an inbox light ware, but no reflex plate.it ahead. Normally lighter for the light collect light is not found. When test object by blocking the light, and the light reflected light, receive part implement received light signals, output a switch signals.Four, I'm the idea of photoelectric sensorWith the development of science and technology people on measuring accuracy had the higher request, this has prompted the pace with The Times photoelectric sensor have updated, improve the main means photoelectric sensor performance is the application of new materials, new technology manufacturing performance is more superior photoelectric element. For example, today the prototype of the photoelectric sensor is a small metal cylindrical equipment, with a calibration lens, transmitter into receiver focused light, the receiver out of cable to the device got a vacuum tube amplifiers in metal cylinder on the incandescent light bulb inside a small as the light source a strong incandescent lamp sensor. Due to the sensor various defects existing in the fields, gradually faded. To appear, because of it of fiber of excellent performance, then appeared with sensors supporting the use of optical passive components, another fiber without any interference of electromagnetic signal, and can make the sensor of the electronic components and other electrical disturbance in isolation. Have a piece of plastic optical fiber core or glass light core, light outside a metallic core skins and bread this layer metal cortical density lower than light core, so low, the beam refraction in the two materials according to the border (incident Anglewithin a certain range, reflected), is all. Based on optical principle, all beams can be made by optical fiber to transmission. Two incident beam Angle in an Angle (along the fiber length direction within) by multiple reflections from the other end after injection, another incident angles than accept the incident light in metal skin, loss. This accept Angle within the biggest incident Angle than two times, this is because fiber slightly larger from air into density larger fiber materials hitting may have a slight refraction. In light of the optical fiber transmission from inside the influence of fiber bending (whether more than bending radius minimal bending radius). Most optical fiber is flexible, easy to install in the narrow space. Photoelectric sensor is a kind of non-contact measurement small electronic measurement equipment, rely on detect its receives the light intensity change, to achieve measurement purposes, andit's also a vulnerable to external disturbance and lose the measurement accuracy of the device. When be being designed so besides the choice optoelectronic components, still must set GSCC signal and temperature compensating measures used to weaken or eliminate the impact of these factors.Photoelectric sensor must pass a light modulation, like radio waves of light modulation of sends and receives, the radio to a station, can ignore other radio signal sensors without modulation long-focal-length only through the use of mechanical shielded, scenes that receiver transmitter only can receive the emission of light, can make its energy becomes very high. In contrast, through modulation transceivers can ignore ambient light, only to own light or with the same modulation frequencies of light without modulation response. The sensor used to test the infrared rays or around the radiation, if just baked red bottle, in this application situation if use other sensor, may be incorrect actions.Photoelectric sensor due to non-contact, high reliability, etc, and to change in measurement, damage the object to be testedSo since its invention in fields since play a significant role, at present it has been widely used in measuring mechanical quantity, thermal quantity, weight, intelligent vehicle system into etc. Now it in power system automatically grid device plays a very important role, because generator input power grid operation often USES accurate with law, must meet: three-phase line sequence is consistent, frequency, phase agree unanimously, voltage amplitude equal, one of the conditions in system design has been satisfied, after three conditions must also meet to grid, of course, artificially grid is more difficult, photoelectric grid is easier.The development of times, science and technology in the update, photoelectric sensor types are increasing and application domain more and more widely, such as a recent kind of infrared already in intelligent vehicle electrical sensors in to the application, one of which had based on infrared sensor is the core of intelligent vehicle, reflective type infrared sensor using reflex infrared sensor design path detection module and speed monitoring module; Another method based on infrared sensor using the car tracing is to collect infrared sensor data.Photoelectric sensor has cannot be replaced by other sensors superiority, so it development foreground is very good, the application will also become more widespread.光电传感器关键字:光电效应 光电元件 光电特性 传感器分类 传感器应用 摘要:在科学技术高速发展的现代社会中,人类已经入瞬息万变的信息时代,人们在日常生活,生产过程中,主要依靠检测技术对信息经获取、筛选和传输,来实现制动控制,自动调节,目前我国已将检测技术列入优先发展的科学技术之一。

P1U1译文

P1U1译文

第一部分电气与电子工程基础第一单元A: 电网络电路或网络由以某种方式连接的电阻器、电感器和电容器等元件组成。

如果网络不包含能源,如电池或电力发电机,那么就被称为无源网络,另一方面,如果存在一个或多个能源,那么组合的结果为有源网络。

在研究电网络的性能时,我们感兴趣的是确定存在于电路的电压和电流。

因为网络由无源电路元件组成,所以必须首先定义这些元件的电特性。

就电阻来说,电压-电流的关系由欧姆定律决定,欧姆定律指出:电阻两端的电压等于电阻上流过的电流乘以电阻值。

在数学上表达为:u = iR式中 u =电压,V ;i =电流,A ;R = 电阻,Ω。

纯电感电压由法拉第定律定义,法拉第定律指出:电感两端的电压正比于流过电感的电流随时间的变化率。

因此可得到:ti Lu d d = 式中 d i/d t = 电流变化率, A/s ; L = 感应系数, H 。

电容两端感应的电压正比于电容两极积累的电荷q 。

因为电荷的积累可表示为电荷增量d q 的和或积分,因此得到的等式为:⎰=q Cu d 1式中电容量C 是与电压和电荷相关的比例常量。

通过定义可知,电流等于电荷随时间的变化率,可表示为i = d q/d t.。

因此电荷增量d q 等于电流乘以相应的时间增量,或d q = i d t.,那么等式 (1-1A -3) 可写为⎰=t i Cu d 1式中 C = 电容量,F 。

等式(1-1A-1)、(1-1A-2) 和 (1-1A-4)表明的三种无源网络形式的概略如图1-1A-1所示。

(1-1A-1) (1-1A-2)(1-1A-3)(1-1A-4)注意,所用为常规电流流程,因此流过每一个元件的电流表示为电压下降的方向。

有源电气设备涉及能量与电能形式的转化,例如,电池中电能从其储存的电能获得,发电机的电能是旋转电枢机械能转化的结果。

有源电气元件存在两种形式:电压源和电流源。

其理想形式为:电压源产生独立于来自电源的电流的恒定电压。

Unit 1 Current, Voltage and Resistance
We shall define voltage “across” an element as the work
done in moving a unit charge (+1C) through the element from one terminal to the other. The term voltage (represented by the letter symbol U) is commonly used to indicate both a potential difference and an electromotive force. The unit in which voltage is measured is the volt(V). One volt is defined as that magnitude of electromotive force required cause a current of one ampere to pass through a conductor having a resistance of one ohm. Besides the volt, smaller or larger magnitude of voltage are expressed in millivolts(mV), microvolts(μV) or kilovolts(kV).

Electric Circuit
Question:
• Which point has a lower potential, A or B?
Electric Circuit
Example:
• Calculate the current through a 3 Ω resistor when a voltage of 12V is applied across it.

•To cause movement of a charge, there must be a potential difference.
(A )
Conventional current has the direction that the (+) charges would have in the circuit.
/eb-media/36/236-004-D4AA985F.gif
• Direct Current • Alternating Current • DC • Provided by • AC
batteries • Provided by power companies
Ammeter
• Measures electric current. • Must be placed in series.
Conventional Current
• By tradition, direction in which “positive charges” would flow.
• Direction is opposite of electron flow.
Question:
What is required in order to have an electric current flow in a circuit?
Question: Why is the ground prong longer than the other two in a plug?
Example: Third rail of subway
/gif/subwaytrack.gif
• Answer: 4 A
Example:
• A 6 Ω resistor has a power source of 20V across it. What will happen to the resistance if the voltage doubles?
Part III
• Factors that affect resistance. • Potentiometer • Voltmeter
Electric Current and Resistance
Physics Mrs. Coyle
Part I
• Basic electric circuit and its diagram. • What causes the flow of electrons in a circuit. • Drift velocity. • Voltaic cell.
Answer:
1. A voltage source. 2. The circuit must be closed.
Battery (Chemical Cell):
• A device that converts chemical energy to electricity. • A battery provides a potential energy difference (voltage source).
What occurs in a wire when the circuit switch is closed?
/HBASE/electric/imgele/micohm.gif
What occurs in a wire when the circuit switch is closed?
Example:
• What happens to the resistance when the length is doubled and the area is quadrupled?
• Answer: It changes by 1/2
Temperature Dependence of Resistance
While the switch is open:
• Free electrons (conducting electrons) are always moving in random motion.
• The random speeds are at an order of 106 m/s. • There is no net movement of charge across a cross section of a wire.
Potentiometer
• A variable resistance. • Used for dimmers, fan speed controls, etc.
Poten
• Measures the voltage between two points in an electric circuit. • Must be connected in parallel.
• Average drift velocity is about 0.01cm/s.
Closing the switch establishes a potential difference (voltage) and an electric field in the circuit.
• Electrons flow in a net direction away from the (-) terminal.
Low Potential
High Potential
Question:
• If the drift velocity is about 0.01cm/s, why do the lights turn on instantaneously when the circuit switch is closed?
• The battery “pumps” positive charges from low (-) to high (+) potential.
Electric Circuit
Resistors use up Energy
• A resistor uses up energy. • When the current goes through the resistor it goes to a lower potential.
• For metals: as temperature increases the resistance increases. At very low temperatures resistance can become zero: superconductivity. • For semiconductors: the opposite occurs.
Voltaic Cell
• Alessandro Volta (1800’s) • Battery
Cu and Zinc Electrodes. Why?
Question: Why is the bird on the wire safe?
Question: Why do electricians work with one hand behind their back?
Resistance
• Depends on type of material, size and shape, temperature. R=ρ L A
L: length of the wire A: cross-sectional area ρ: resistivity (inherent to material)
Example:
• What charge flows through a cross sectional area of a wire in 10min, if the ammeter measures a current of 5mA?
• Answer: 3C
Resistance
• Resistance of an object to the flow of electrical current.
A voltmeter is connected in parallel.
Ammeter
• Measures electric current. • Must be placed in series.
• R= V / I • Resistance equals the ratio of voltage to current. • Unit: Ohm (Ω)
Ohm’s Law (Georg Ohm, 1787-1854)
V = IR
• The voltage , V, across a resistor is proportional to the current, I, that flows through it. • In general, resistance does not depend on the voltage.
