What is resistivity of a wire ? What are the physical conditions on which resistivity of metal depen ?

Explanation

Resistivity of a material of a conductor is equal to the resistance of the unit cube of the material of the conductor .
1. Resistivity of a conductor depends upon the temeperature of the conduct also If the temperature of a conductor increases , its resistivity also increases . If the temperature of a conductor decreases , its resistivity also decreases .
2. It depends on the nature of the material and its temeprature .
