What is the difference between electric potential energy and electric potential?

Electric potential energy (also known as "electrostatic potential energy") is a potential energy associated with the conservative Coulomb forces within a defined system of point charges. The electrostatic potential energy of the system (UE), relative to the zero or the reference level, is equal to the total work W that must be done by a hypothetical external agent in order to bring the charges slowly (no change in kinetic energy), one by one, from infinite separation to the desired system configuration. The electric potential (denoted by f, fE or V; also called the electrostatic potential) at a point in space is potential energy divided by charge that is associated with a static electric field. It is a scalar quantity, typically measured in volts.

Dear Student, Electric potential energy (also known as "electrostatic potential energy") is a potential energy associated with the conservative Coulomb forces within a defined system of point charges. The reference zero is usually taken to be a state in which the individual point charges are very well separated ("are at infinite separation") and are at rest. [1]:§25-1 The electrostatic potential energy of the system (UE), relative to this zero, is equal to the total work W that must be done by a hypothetical external agent in order to bring the charges slowly (so that Kinetic energy doesn't change), one by one, from infinite separation to the desired system configuration. On the other hand, The electric potential (denoted by f, fE or V; also called the electrostatic potential) at a point in space is potential energy divided by charge that is associated with a static (time-invariant) electric field. It is a scalar quantity, typically measured in volts. V = U/q These are the general definitions required upto this level. For further knowledge you can always refer a good book. Thanks Avijit Arya
