प्रश्न
Define the term polarization of a dielectric and write the expression for a linear isotropic dielectric in terms of electric field.
उत्तर १
Net dipole moment per unit volume induced in dielectric is called polarization. It is represented by P.
P = χeE
P = Polarisation
χe → Electrical succeptibility
E = External electric field.
उत्तर २
Dipole moment per unit volume of a polarized dielectric is known as the polarization of a dielectric. It is denoted by the letter P for the linear isotropic dielectric.
