Question

The resistivity of a material is 2x10-3Ωm. What is the conductivity\n​

Answer 1

Answer:

Conductivity, $\sigma=500\ (\Omega-m)^{-1}$

Explanation:

Given that,

The resistivity of a material, $\rho=2\times 10^{-3}\ \Omega-m$

We need to find the conductivity of the material.

We know that the reciprocal of resistivity is called conductivity.

$\sigma=\dfrac{1}{\rho}\\\\\sigma=\dfrac{1}{2\times 10^{-3}}\\\\\sigma=500\ (\Omega-m)^{-1}$

So, the conductivity of the material is $500\ (\Omega-m)^{-1}$.
