In the power supply, when the non electrostatic force moves the positive charge from the negative plate to the positive plate, it has to do work on the charge. The physical process of doing work is the essence of generating the electromotive force of the power supply. The work done by the non electrostatic force reflects how much other forms of energy has become electric energy. While the external electric energy has been transformed into other forms of energy. The total energy released by the power supply is equal to EQ, so the unit charge is positive The total energy released in the internal and external circuits depends on the electromotive force of the power supply
