电工技术复习题
《电工电子技术》复习题说明:一、本复习题仅适用机电、机制专业期末复习参考使用,不能作为考试范围或重点。
二、复习题中答案及说法仅供参考,当与教材不一致时,以现用教材为准。
第1章直流电路复习题一、填空题:1、电源和负载的本质区别是:电源是把其它形式的能量转换成电能的设备,负载是把电能转换成其它形式能量的设备。
2、电路的组成包括电源、负载和传输环节。
3、对电阻负载而言,当电压一定时,负载电阻越小,则负载越大,通过负载的电流和负载上消耗的功率就越大;反之,负载电阻越大,说明负载越小。
4、元件上电压和电流关系成正比变化的电路称为线性电路。
5、电源向负载提供最大功率的条件是电源内阻与负载电阻的数值相等,这种情况称为电源与负载相匹配,此时负载上获得的最大功率为U S2/4R S。
6、电压是产生电流的根本原因。
电路中任意两点之间电位的差值等于这两点间电压。
电路中某点到参考点间的电压称为该点的电位,电位具有相对性。
7、电压的实际方向规定为从高电位指向低电位,其方向可用箭头表示,也可用“+”“-”极性表示。
8、已知电路中A点的对地电位是35V,B点的对地电位是10V,则U BA= -25 V。
9、在电路分析计算中,当假定的电流方向与实际方向相反时取负。
假定的电流、电压方向称作电流、电压的参考方向。
10、3个等值电阻并联,其等效电阻是3KΩ。
如果把这2个电阻串联,那么它们的总电阻是 18Ω。
11、设电源电压为U s,内阻为R0,则电源短路时,电源端电压U= 0 ,电源电流I= Us/R 。
12、已知某元件上的电流电压如图所示,则该元件消耗的功率是 12W,此元件是负载(电源还是负载)。
+ U-rRI=4A二、判断正误:1、恒压源接任何负载,其端电压为定值。
( 对 )2、电源内部的电流方向总是由电源负极流向电源正极。
( 错 )3、大负载是指在一定电压下,向电源吸取电流大的设备。
( 对 )4、电路中任意一点的电位值随着参考点的改变而改变,而电路中任意两点的电压与参考点无关。
