Question

Distinguish between the resistivity and conductivity of a conductor.

Answer 1

Resistivity	Conductivity
1. It is the resistance of a conductor of unit length and unit area of cross-section.	1. It is the reciprocal of the electrical resistivity of a material.
2. Its unit is ohm metre	2. Its unit is ohm-1 meter-1 or mho metre-1
3. It is the measure of the resisting power of a specified material to the passage of an electric current.	3. It is the measure of its ability to pass the current through it.
