WebThe permittivity of a medium is expressed as the product of the dielectric constant and the free space permittivity: [Equation 3] The dielectric constant is always greater than or equal to 1.0. This means the E-field in Equation [2] is always reduced relative to what the E-field would be in free space [Equation 1]. http://www.differencebetween.net/science/physics-science/difference-between-dielectric-constant-and-permittivity/
