The Function of Inductors in Circuits
An inductor is a coil of wire that stores energy in a magnetic field when an electric current flows through it. Its inductance determines how well it can store this energy. Inductors are used to filter signals, store energy, and manage current in circuits. The stored magnetic energy in an inductor resists changes in the current flow, which can smooth out abrupt changes and make inductors useful as filters or in inductor-capacitor circuits.
