Conductivity, Electrical


(or conductivity), a physical quantity equal to the electrical conductance of a cylindrical conductor of unit length and unit cross-sectional area. The relation between conductivity σ and resistivity ρ is given by the equation σ = 1/p. Conductivity is usually measured in units of mho/m or mho/cm. The mho, also called the Siemens, is equal to the reciprocal of the ohm.
