五、根据下列方框中所给的词填空（5X1=5,共5分）

Resistance in a material arises from the collision of electrons with the atoms and with each other as they move. The ___ 1、 collisions ___ produce heat, increasing the temperature of the material. Consider the ordinary toaster. Current flows through the ___2、wires ___ of the power cord and through the toaster's filament (the glowing wire you see inside). The same current must flow in the power cord as flows through the filament. The cord has very little ___ 3、resistance ___, while the filament has considerably more. Since the filament has a much higher resistance than the cord, it ___ 4、produces ___ much more heat. That's as it should be. You want the heat for your toast, but you do not want the power cord getting ___ 5、hot ___!

The standard incandescent light bulb is another example. The filament in the light bulb glows
