Permittivity Maxwell's Equations

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]. The permittivity is a measure of this reduction. The permittivity of common materials is given in Table 1. TABLE I. Common Values for the Dielectric Constant.
