What is Electrical Conductivity?
Electrical conductivity (κ) is the measure of a material's ability to conduct electric current. It is the reciprocal of electrical resistivity (ρ). In solutions, conductivity depends on the concentration and mobility of ions. Strong electrolytes have high conductivity. Metals have the highest conductivity due to freely moving electrons. The unit is siemens per metre (S/m).
