Dielectric Constant

A number that describes the dielectric strength of a material relative to a vacuum, which has a dielectric constant of one. Relative permittivity. It is the ratio of the capacitance of a capacitor with the given material as dielectric, to the capacitance of the same capacitor with vacuum (or air) as the dielectric. That property of a dielectric that determines the electrostatic energy stored per unit volume for a unit potential gradient.
