Frequent question: How do you calculate electric potential at a point due to an electric dipole?

What is the potential at center of dipole?

Potential at the center of an electric dipole is zero.

What is the electric potential between two opposite charges?

Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero.

What is the value of potential on Equatorial point of dipole?

Thus, the electric potential is zero on the equatorial line of a dipole (but the intensity is not zero).
