Comprehending Capacitors and Inductors
Capacitors and inductors are two fundamental components employed in electronic circuits. A capacitor is a passive component that stores electronic energy in an electric field. It consists of a pair of conductive plates isolated by a dielectric material. When a voltage is supplied across the capacitor's plates, an charge builds up, storing energy. Inductors, on the other hand, store energy in a magnetic field. They consist of a coil of wire, and when current flows through the coil, it generates a magnetic field around the wire. The strength of this magnetic field depends on the amount of current flowing and the number of turns in the coil.
