Answer : Restivity is a measure of a materials ability to oppose the flow of current.

Resistivity of a conductor is a properly of the material of the conductor. Unit of resistivity is Ohm metre .

Resistivity of the material of the conductor changes with temperature.

For Example :

Restivity copper is 1.7 × 10 m at room temperature.

There is nothing called resistivity of a circuit .

Below is the equation resistivity (p) and resistance ( R) of a conductor of length ( L) an area ( a)

R = p 1 / A
