Electrical resistivity is the reciprocal of electrical conductivity. It is the measure of the ability of a material to oppose the flow of current.
Metals are good conductors of electricity. Hence, they have low resistivity.
The insulators like rubber, glass, graphite, plastics, etc. have very high resistivity when compared to metallic conductors.
The resistivity of a conductor is given by:
where, R = Resistance
ρ = Resistivity
A = Area
l = Length
Resistivity is a material property of the conductor. It depends only on the material of the conductor and not on the length or area of the material.
