Electrical resistivity and conductivity - Wikipedia
Electrical 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.
Electrical Conductivity | Definition, Symbol, Formula, Unit
The symbol of electrical conductivity is symbolized with a Greek Letter σ (Signa). The electrical conductivity is inversely proportional to the electrical resistivity (ρ). The relation between conductivity and resistivity is given below. σ = 1/ ρ.
