  • 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
  • Conductivity | Electricity, Resistance Ohm’s Law | Britannica
    Electrical conductivity is the current or the quantity of electricity passing per second through a similar slab when the potential gradient is unity, and it is the reciprocal of the resistivity
