Which of the following components store energy in the form of electrical charges?
Capacitors
Thus, capacitors store energy in the form of electrical charges. We have examined capacitors, transformers, resistors, and inductors. Capacitors store energy by accumulating electrical charges on plates, creating an electric field.
