Electric Potential

Definition - What does Electric Potential mean?

Electric Potential, also known as electric field potential or electrostatic potential is the amount of work done by an external force on a unit charge by moving it from a reference point to the point in question inside an electric field without causing any acceleration in the unit charge. Electric potential is a scalar quantity denoted by ā€˜Vā€™ and is the potential of an electric field at any point inside the field.

Petropedia explains Electric Potential

The electric potential for a positive charge will decrease if it moves with an electric field and increase if it moves against the electric field. When the charge is moved in the direction of the field, no work is required to be done by the external force and the charge would move due to its own stored energy thereby reducing the potential energy of the charge. Thus the electric potential at any point within the electric field would be the amount of work done on a unit positive test charge by moving it from a reference point to the point in question without causing acceleration. The reference point is taken a point on earth or at infinity. Electric potential is always equal to the electric potential energy of a charged particle divided by the charge of that particular particle.
