WebOct 26, 2024 · Dielectric polarization is the term given to describe the behavior of a material when an external electric field is applied on it. A simple picture can be made using a capacitor as an example. Figure shows an example of a dielectric material in between two conducting parallel plates. Webthe dielectric strength of a solid dielectric increases very rapidly to an upper limit called the intrinsic electric strength. Intrinsic breakdown depends upon the presence of free electrons which are capable of migration through the lattice of the dielectric.
