Basic Principles of Capacitors At the heart of a capacitor bank lies the capacitor itself. A capacitor is an electrical component that stores energy in an electric field, created by a pair of conductive plates separated by an insulating material known as a dielectric. When voltage is applied across the plates, an electric charge accumulates, allowing the capacitor to store energy. 1. Definition and Function Capacitors serve various functions in electrical circuits, including energy storage, filtering, and timing applications. They can release stored energy quickly, making them invaluable in applications requiring rapid bursts of power. 2. Types of Capacitors There are several types of capacitors, including ceramic, electrolytic, tantalum, and film capacitors.
