Question

define resistivity.on which factors does it depend and write it's mathamatical relation​

Answer 1

Explanation:

The resitivity of the material is the resistance of that conductor in per unit length and per unit cross sectional area. Resistivity of a material is depends upon the factors

Answer 2

Hello mate ...

Definition

• The electrical resistivity is the electrical resistance per unit length and per unit of cross-sectional area at a specified temperature...

It depends on The cross section area and lengths of object and is denoted by "rho"...

r = E/ J

Electrical resistivity is a key parameter for material that are to be used with electrical and electronic systems...
