Inductors

Inductors are two-terminal, passive electronic components that can be classified as coils, reactors or chokes. They are used in a wide variety of electrical circuits and systems to store energy in the form of a magnetic field. When current flows through an inductor, it creates a magnetic field that opposes any sudden changes in current flow. This is known as inductance and allows the inductor to act like an air gap and prevent large surges of electrical power from damaging other components.

Inductors have countless applications including power supplies, signal filters, oscillators, pulse generators and low-pass filters. In terms of physical characteristics, modern inductors often resemble cylindrical coils of wire with leads on either end for connecting to other components within a circuit. The size and shape of the coil alters its inductance as well as other properties such as resistance and capacitance which affects its functionality within a particular circuit.
