Electrical conductance is an electrical phenomenon where a material contains movable particles with electric charge, which can carry electricity. When a difference of electrical potential is placed across a conductor, its movable charges flow, and an electric current appears.
The unit of electricalconductivity involves the reciprocal of resistance (1/ohm or mho) and a distance, and is mho cm-1.
Electricalconductivity and dielectric breakdown voltage of oils are important in lubricated components subjected to stray or self-generated electric currents.
Electricalconductivity or its reciprocal, resistance, is measured with an apparatus which determines the current flowing through an oil between immersed electrodes at a constant distance apart.
Electricalconductivity or specific conductivity is a measure of a material's ability to conduct an electric current.
The conductivity of a semiconductor is generally intermediate, but varies widely under different conditions, such as exposure of the material to electric fields or specific frequencies of light, and, most important, with temperature and composition of the semiconductor material.
