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.
In the case of electrical energy, the object is the charged particle, and the position is within the electric field. Another way of looking at electrical energy is electrical potential, which is measured in volts. Electrical energy is used to move charges through wires to create current, or electricity.
