This article provides overview of common and less common inductor symbols.
An inductor, also called a coil, choke, winding, inductance or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil.
Circuit Schematic Symbols of Inductors
There are many different symbols that are used to represent inductors. The most common one is a coil of wire, but you may also see symbols that represent a solenoid or a spiral.
