Question

What is resistivity ? Write its unit. On what factors do resistivity depend ?​

Answer 1

Answer:

The resitivity of the material is the resistance of that conductor in per unit length and per unit cross sectional area. SI Unit of Resistivity is ohm- metre.

Answer 2

$\huge\blue{\mid{\fbox{\tt{Answer}}\mid}}$

Resistivity : A measure of the resisting power of a specified material to the flow of an electric current. The resistivity of the material is the resistance of that conductor in per unit length and per unit cross sectional area.

The SI unit of Resistivity is a ohm.

Resistivity depends upon the following factors:

1) On its nature.

2)temperature of the conductor.
