Inductors/Coils/TransformersInductors, also known as coils or transformers, are passive electronic components that are used to store energy in the form of a magnetic field. Inductors consist of a coil of wire, which creates a magnetic field when an electric current is passed through it. The strength of the magnetic field depends on the number of turns of wire in the coil, the size of the coil, and the type of material used for the wire. Inductors are commonly used in electronic circuits to filter signals, store energy, and provide electromagnetic shielding. They are also an essential component of many types of electrical transformers, which are used to increase or decrease the voltage of an electrical signal.
