Question

What is the resistivity of Copper?

(a) 1.59*10^-8ohm-m

(b) 2.7*10^-8ohm-m

(c) 7.3*10^-8ohm-m

(d) 5.35*10^-8ohm-m

I got this question in my homework.

My question is based upon Resistivity topic in division Simple DC Networks of Basic Electrical Engineering

Answer 1

Right answer is (a) 1.59*10^-8ohm-m

The explanation is: Resistivity is a material property. Different materials have different resistivity. Resistivity of copper is 1.72*10^-8 ohm-m.
