Electrical resistivity and conductivity - Wikipedia
WebElectrical conductivity (or specific conductance) is the reciprocal of electrical resistivity. It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter σ ( sigma ), but κ ( kappa) (especially in electrical engineering) [citation needed] and γ ( gamma) [citation needed] are sometimes used.
