WebElectric permittivity is a measurement of the degree to which a material or medium is polarized in the presence of an electric field. Permittivity of free space ε 0 is a constant value equal to 8.85 × 10 − 12 C N m 2. The permittivity of matter differs from that of vacuum, which stems from its atomic composition and arrangement.
