Discuss the role and applications of capacitors... - SS2 Physics Electronics Question

Capacitors are electronic components used to store and release electrical charge in a circuit. They consist of two conductive plates separated by a dielectric material. When a voltage is applied across the plates, charge accumulates on each plate, resulting in the storage of electrical energy. Capacitors are used in various applications, such as energy storage, timing circuits, noise filtering, and coupling capacitors. They are commonly employed in power supply circuits to smooth out voltage fluctuations and stabilise the output. Capacitors also play a crucial role in AC circuits, where they can block DC signals and allow the passage of AC signals.
