WebThe dielectric constant of a substance can be defined as: The ratio of the permittivity of the substance to the permittivity of the free space It expresses the extent to which a material … The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field. Permittivity is a material's property that affects the Coulomb force between two …
