Inductors, coils, and chokes are electronic components that are used to store and control electrical energy in a circuit.
An inductor is a passive electronic component that stores energy in a magnetic field when current flows through it. It is typically made of a coil of wire wound around a core made of magnetic material, such as iron or ferrite. The inductance of an inductor is a measure of its ability to store energy in a magnetic field and is measured in henries (H).
Coils and chokes are similar to inductors but are designed to provide additional functions. A coil is typically a winding of wire that is used to produce a magnetic field, while a choke is an inductor designed to block high-frequency alternating currents while allowing low-frequency currents to pass through.
Inductors, coils, and chokes are used in a wide range of applications, including power supplies, filters, oscillators, and radio frequency circuits. They can be used to store energy, smooth voltage and current levels, filter out unwanted frequencies, and provide impedance matching, among other functions.
Different types of inductors, coils, and chokes are available for different applications, including air-core inductors, ferrite-core inductors, toroidal inductors, and surface-mount inductors, among others. The choice of inductor or coil depends on the specific application and the desired electrical properties of the circuit.
