Potential due to an Electric Dipole
The electric potential is the work required to move a unit of positive charge from a reference point to a particular point within an electric field having no acceleration. A dipole is referred to as a pair of opposite charges having equal magnitudes that are separated by a distance, d.
Electric potential (V) at a point due to an electric dipole is given by the following expression:
V = k.p.cos θ/ r2
where
- [Tex]k = 1/4\pi\epsilon_\omicron[/Tex], k is Coulomb’s constant
- p is the magnitude of electric dipole, given by p = q.d
- θ is the angle between the dipole moment vector p and the position vector, r .
This formula tells us that the electric potential due to an electric dipole decreases with the square of the distance r and depends on the angle between the dipole moment and the position vector.
Potential due to an Electric Dipole
The potential due to an electric dipole at a point in space is the electric potential energy per unit charge that a test charge would experience at that point due to the dipole. An electric potential is the amount of work needed to move a unit of positive charge from a reference point to a specific point inside an electric field without producing acceleration. In this article, we will discuss the potential due to an electric dipole and its derivation.
