Capacitors can help stabilize voltage and current levels in a circuit. They can store and release energy quickly, making them ideal for maintaining stable voltage levels in power supply circuits or buffering current spikes in high-speed digital circuits.

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.
