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
