Diëlectric

Electric potential of a polarized material

The potential due to a polarized diëlectric is given by

where is the electric polarization density, and and are the surface and volume bound charge densities respectively given by

If additional free charge is present, the principle of superposition may be used to combine the potentials due to free charge and due to polarization (i.e. bound charge).

Derivation

Applying ^GE1

as required.
