How does a capacitor store energy?

When a voltage is applied across a capacitor, it accumulates charge on its plates, creating an electric field that stores energy. This stored energy can be released later when the voltage is removed, making capacitors useful in applications such as power supplies, energy storage systems, and backup power sources.
