Dipole System

Assume that -q and q being two charges with the same amount of energy but opposite directed. If the distance (very little separation) between the two charges is d, the voltage V between -q and q will be expressed as:

where P = qd and R is the vector from the middle of d to the point where the voltage is measured.
