Question

6. The resistance of a conductor of
length x is r. If its area of cross-
section is a, what is its resistivity?
What is its unit?.


please give me correct answer............

if you answer me correct then only I will mark you as brainlisit..............​

Answer 1

Explanation:

Resistivity can be defined as the measure of resistance of a specific material of specific size.

It can be calculated by resistance x cross-sectional area/ length of the conductor = ra/x.

SI unit of resistivity is ohm.metre.
