Answer: The electric dipole moment is considered as the measure of separation of positive as well as negative electrical charges inside a system. Therefore, this is the measure of the total polarity of the system. An electric dipole moment is known to be the first-order term of the multipole expansion. An electric dipole moment contains two equal as well as opposite charges that are known to be infinitesimally close together. However, real dipoles consist of separated charges. The S.I unit of electric dipole moment is known to be the ampere second meter.
