Inductor
Inductor
An Inductor (pronounced: /ɪnˈdʌktər/) is a passive electronic component that stores energy in its magnetic field. It is often used in electronic circuits to block or filter high-frequency signals.
Etymology
The term "Inductor" is derived from the verb "induce", which in the context of electronics, refers to the generation of an electric current or electric field due to a changing magnetic field.
Description
An inductor is typically made of a coil of conducting material, like copper wire, around a core material. When an electric current passes through the coil, it creates a magnetic field around the coil. The strength of this magnetic field is proportional to the current passing through the coil and the number of turns in the coil.
