Question

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

Answer 1

Conductivity,
`\sigma=500\ (\Omega-m)^(-1)`

Step-by-step explanation:

Given that,

The resistivity of a material,
`\rho=2* 10^(-3)\ \Omega-m`

We need to find the conductivity of the material.

We know that the reciprocal of resistivity is called conductivity.

`\sigma=(1)/(\rho)\\\\\sigma=(1)/(2* 10^(-3))\\\\\sigma=500\ (\Omega-m)^(-1)`

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