Perfect electric dipole

A perfect electric dipole with electric dipole moment is an idealized charge distribution in electrostatics whose Multipole expansion of the electrostatic potential has all terms vanish except for the dipole term. Thus the potential due to a perfect dipole located at is

and given a continuous distribution of perfect dipoles localized to

A perfect dipole arises by considering a physical dipole in the limit as and so that remains fixed.
