👉 Capacitors are electronic devices that store and release electrical charge. They are commonly used in circuits to store energy, as well as in applications such as batteries, where they can be used to provide a constant supply of electricity. Capacitors consist of two plates with oppositely charged electric charges on them, separated by a distance called the capacitance. When the capacitor is connected across a circuit, it stores electrical charge and releases that charge when an external voltage source is applied. Capacitors are
