    1. The problem statement, all variables and given/known data
    What's the difference between electric potential energy and electric potential?

    Can someone explain these concepts, simply? I don't understand any definitions I've found on the internet. Any help would be appreciated.

    2. Relevant equations
    N/A

    3. The attempt at a solution
    N/A

    Hello S.R. Welcome to PF.

    electric potential energy is Potential Energy due to an electric field. It is usually applied to a particle or system of particles.

    electric potential is a somewhat different concept. It can be defined as the Potential Energy per unit charge for a charged particle due Electric Field. In other words, it's the electric potential energy at a particular location that a particle with a unit charge would have.

    Those are off the top of my head, so I hope my head's on straight tonight. :smile:

    Thanks, Sammy. Is electric potential referred to as voltage?

    It often is referred to as voltage in electric circuits.

    I go along with SammyS. The unit of potential is JOULE per COULOMB and the unit of potential energy is JOULE.
    Potential refers to a region of space if you like and potential energy refers to a charge brought into the space.
    There is a direct analogy with gravitation.
    The unit of gravitational potential is JOULE per kg
    The unit of gravitational potential energy is JOULE
    Hope this helps
