DIELECTRIC POLARIZATION

The process of producing electric dipoles, which are oriented along the field direction, is called polarization in dielectric. Dielectric polarization is also the displacement of charged particles under the action of the external electric field. Hence it is useful is making circuits, capacitors etc. VARIOUS POLARIZATION PROCESSES: Ionic polarization. Orientational polarization. Electronic polarization. Interfacial/ Space … Read more
