Resistivity of conductors (ρ)
Resistance per unit length per unit cross sectional area of a material is called its resistivity or specific resistance, for metals it is (a) .
Its reciprocal is called conductivity or specific conductance (σ). Both ρ & σ are independent of length, thickness, & shape or geometry.
