Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is a property of a material; it quantifies how strongly the material opposes the flow ofelectric current. A low resistivity indicates a material that readily allows the movement of electric charge. The SI unit of electrical resistivity is the ohm⋅metre (Ω⋅m). It is commonly represented by the Greek letter ρ (rho).

Electrical conductivity or specific conductance is the reciprocal quantity, and measures a material's ability to conduct an electric current. It is commonly represented by the Greek letter σ (sigma), but κ (kappa) (especially in electrical engineering) or γ (gamma) are also occasionally used. Its SI unit is siemens per metre (S⋅m−1) and CGSE unit is reciprocal second (s−1).
