An electric dipole is a pair of equal and opposite charges separated by a small distance. The product of the charge and distance between them is called the dipole moment, which represents the strength of the dipole. The electric field generated by the dipole is proportional to the dipole moment. The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system, that is, a measure of the system's overall polarity. The SI unit for electric dipole moment is the coulomb-meter (C⋅m)
