    Electric Dipole: Potential And Electric Field Due To Dipole, Lecture-9.

    An electric dipole is a system of two equal and oppositely signed charges +q and -q separated by a distance d. Atomic phenomena can often be modelled in terms of dipoles, so its important to study the dipole in detail. The electrostatic potential for such an arrangement (i.e. a dipole) can easily be written; Its…
