What is specific resistance or resistivity of the material?
by

1 Answer

Answer :

Specific resistance of the material is the resistance of a piece of unit length and unit cross-section (unit cube of that material). That is the resistance between the opposite faces of unit cube of the material. Or the specific resistance of any material is the resistance offered by the opposite face of that material. The unit of specific resistance is Ω/cm3 , Ω/inch3 , Ω/m3 .
