Electric Potential

Electric Potential Energy and Electric Potential. These two terms are NOT the same. Electric Potential Energy can be defined as a potential energy (measured in Joules) that results from coulomb forces and is associated with the configuration of a set of charges within a system. In other words, electric potential energy is used to describe the potential energy in systems with electric fields that change with time. While electric potential energy has a dependency upon the charge of the object experiencing the electric field, electric potential is purely location dependent. Electric potential is the potential energy per charge. The equation for electric potential is  EP=PE/Q. How is this related to circuits? well, I believe a battery powered electric circuit has locations of high and low potential, and charge moving through the wires of the circuit will encounter changes in electric potential as it traverses the circuit. It's all kind of complicated.
