Electric Field Due to a Short Dipole – formulas
In this post, we will study 2 formulas of the electric field due to a short dipole.
These electric field formulas represent the following:
(1) Electric Field Due to a Short Dipole at a point P on its axis &
(2) Electric Field Due to a Short Dipole at a point on the equatorial line.
