Electric induction dielectric field
Webelectronic polarization ( Pe ), consisting of the induction of atomic dipoles through shifts of electrons with respect to the atomic nuclei; (b) atomic (or ionic) polarization ( Pa ), that is, the reciprocal displacement of different atomic nuclei of a molecule from their original, relative positions, with induction of molecular dipoles; (c) WebThe SI unit of electric displacement is Coulomb per meter square (C m-2). The mathematical representation is as follows: D ≡ ϵ 0 E + P. Where, ϵ0: Vacuum permittivity. P: Polarization density. E: Electric field. D: Electric displacement field. It was found that if electric field E is applied on the dielectric material, the bound charges ...
