Question

Quizplus · Accepted Answer

The resistivity of any given metal depends on its temperature, which means it varies with temperature. It is defined as the proportionality constant between the resistance R and the ratio of the length L to the cross-sectional area A of a wire made of the metal. The unit of resistivity is ohm-meter. Therefore, all the given options are correct, and option E is the best choice.
