Relative permittivity - Wikipedia

The relative permittivity, or dielectric constant, of a material is its absolute permittivity expressed as a ratio relative to the vacuum permittivity.. Permittivity is a material's property that affects the Coulomb force between two point charges in the material. Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum.
