Question

what is defination of resistivity of a conductor

Answer 1

The resistivity of substance does not depend on length and thickness. It depends on the nature of substance and temperature.

Answer 2

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is a fundamental property that quantifies how strongly a given material opposes the flow of electric current. A lowresistivity indicates a material that readily allows the flow of electric current.
