An electric current carries electrons from an area of high  potential to another area of low potential. Potential difference is  the condition that must exist for a current â¦ to move electrons  around.
If the electric charge of an object can be assumed to be at rest, then it has potential energy due to its position relative to other charged objects. The electrostatic potential energy is the energy of an electrically charged particle (at rest) in an electric field.
