An electrical conductor is a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage. Conductivity, in general, is the capacity to transmit something, such as electricity or heat. Pure elemental silver is the best electrical conductor encountered in everyday life. Copper, steel, gold, aluminum, and brass are also good conductors.

We have to note the following relations for electronic conductors,

Molar conductivity,${\Lambda }_m=\frac{\kappa }{C}$

$G^{\ast }=\frac{l}{A}$

Electrical conductivity,$\kappa =\frac{G^{\ast }}{R}$

Resistance,$R=\frac{\rho l}{A}$
