Capacitors are key components in electrical and electronic circuits, known for their ability to store and release electrical energy. They do this by accumulating charge in an electric field between two conductive plates, with the amount of energy they can store being measured in farads (F). Capacitors serve multiple roles in circuits: they can smooth out or filter electrical signals, compensate for power supply fluctuations, and even tune resonant circuits in radio frequency applications. They come in a vast array of types and values, including ceramic, electrolytic, and tantalum capacitors, each having unique characteristics suitable for specific applications.
