Electric dipole moment is charge times displacement

The vector of electric dipole moment is a vector whose magnitude describes the electric dipole moment of the system. It is collinear to the vector connecting the two point charges.

Conditions:

  1. The charges must be equal by magnitude and have opposite signs.
