Question

Define resistivity of a material. Does it depend on temperature?

Answer 1

Resistivity is known as specific electrical resistance or volume resistivity. It can be defined as the intrinsic property of a given material that shows how it opposes the flow of current. It can also be defined as the resistance offered by a conductor having unit length and unit area of cross section.

The unit for resistivity is the ohm-metre.

The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.
