Of, relating to, or concerned with electricity; electric.
Fr.: conductivité électrique
A measure of a material's ability to conduct an electrical current. It is the reciprocal of the → resistivity. Conductivity is expressed by σ = ne2l/(2mv), where n is the number of electrons per cm3 volume of the → conductor, e is the → electron charge, l is the → mean free path, m is the → electron mass, and v is the arithmetic mean velocity of thermal motion of electrons at a given temperature.
Fr.: réseau électrique
An arrangement of the various electrical energy sources with interconnected electrical devices.
