electrical conductivity

Electrical conductivity or specific conductivity is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of the current density  to the electric field strength :.

Compare with resistance .A measure of how easily an electric current can pass through a material. The conductivity is the reciprocal of the resistance . The SI unit of conductance is the siemens .
