WebElectrical Conductivity (σ) and Resistivity (ρ) Electrical conductivity is the proportionality factor relating to the current that flows in a medium to the electric force field that is applied. It is a measure of the ability of the material to conduct an electrical current to move through the material. Resistivity is the reciprocal of ... WebElectrical conductivity is an inherent property of most materials and ranges from extremely conductive materials, such as metals, to non-conductive materials, like plastic or glass. In between the two extremes are aqueous solutions, such as sea water and plating baths.
