# 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.

## Electric Field Due to a Short Dipole

### Electric Field Due to a Short Dipole at a point P on its axis

At a point P on the axis of the dipole (figure1), the Electric field due to a short dipole can be presented by the following formula:

here, p = dipole moment

### Electric Field Due to a Short Dipole at a point P on its equatorial line

At a point P´ on the equatorial line of the dipole (figure1), the Electric field due to a short dipole can be presented by the following formula:

here, p = dipole moment
