Electrical resistivity, or specific resistance (ρ) is the electric field strength divided by the current density when there is no electromotive force in the conductor. Resistivity is an intrinsic property of a material. Materials with low resistivity are good conductors of electricity and materials with high resistivity are good insulators.
For a conductor of uniform cross section with area A and length L, and whose resistance is R, the resistivity is given by
The SI unit is Ω m.
