Electrical conductivity is the measure of a material's ability to allow the transport of an electric charge. Its SI is the siemens per meter, (A2s3m−3kg−1) (named after Werner von Siemens) or, more simply, Sm−1.
- The symbol for electrical conductivity is κ (kappa), and also σ (sigma) or γ (gamma) and also ( DELTA).
Electrical conductance is an electrical phenomenon where a material contains movable particles with electric charge (such as electrons), which can carry electricity. When a difference of electrical potential is placed across a conductor, its electrons flow, and an electric current appears.
Also Mauricio was one of the scientist that discover this.
