Definition of Inductors

An inductor is a coil of wire that stores energy as a magnetic field. The coil is usually wrapped around an iron-containing core, which increases the amount of energy that can be stored by the inductor.

Circuit symbol:Inductance Symbol: L, unit: henry (H)

Inductance is the proportionality factor that relates voltage, V, to the rate of change of current, dI/dt, through an inductor.
