WebIn electromagnetism, permittivity, which is also known as absolute permittivity, is a measure of the electric polarizability of a dielectric or an insulator. The permittivity also characterizes the ability of the dielectric to store electric energy in an electrical field. WebThe dielectric constant k is the relative permittivity of a dielectric material. It is an important parameter in characterizing capacitors.It is unfortunate that the same symbol k is often used for Coulomb's constant, so one must be careful of this possible confusion.It is more typical of physics texts to use the form 1/4πε 0: for Coulomb's constant.
