How is energy stored in a capacitor

Webstored in a capacitor is electrostatic potential energy and is thus related to the charge and voltage between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. Web5 jun. 2015 · As the current rises, energy is stored in the inductor' s magnetic field. When the capacitor reaches full charge, the inductor resists a reduction in current. It generates an EMF that keeps the current flowing. The energy for this comes from the inductor's magnetic field. Capacitors and inductors store energy. Only resistance is disipative.
