Electrical energy. Electrical energy is energy related to forces on electrically charged particles and the movement of those particles (often electrons in wires, but not always). This energy is supplied by the combination of current and electric potential (often referred to as voltage because electric potential is measured in volts) that is
Q = amount of charge stored when the whole battery voltage appears across the capacitor. V= voltage on the capacitor proportional to the charge. Then, energy stored in the battery = QV. Half of that energy is dissipated in heat in the resistance of the charging pathway, and only QV/2 is finally stored on the capacitor.
