Question

name the unit of resistivity ????????????

Answer 1

Hey mate !!

Here's your answer !!

Resistivity can be defined as the resistance of a particular material in a given temperature and pressure with specified length and area of cross-section. The formula for resistivity is as follows:

[tex]p = R \frac{l}{a} [/tex]

Here ' p ' denotes Resistivity, ' R ' denotes resistance, ' l ' denotes length
and ' a ' denotes area of cross section.

Since Resistivity is mainily length / area * Resistance.

So SI unit = Ohms * metre / metre²

= Ohms * 1 / metre 

= Ohm meter.

Hope my answer helped you !!

Cheers !!
