# Inductor Impedance Calculator

The inductor impedance calculator calculates the impedance of an inductor based on the value of the
inductance, L, of the inductor and the
frequency, f, of the signal passing through the inductor,
according to the formula, **X L= 2πfL**.

A user enters the inductance, L, and the frequency, f, and the result will automatically be calculated and shown. The impedance result which is displayed above is in unit ohms (Ω).

The impedance calculated is a measure of the inductor's resistance to a signal passing through. Inductors have higher impedance to higher frequency signals; and, conversely, they
have
lower impedance to signals of lower frequency. This means that lower frequency signals will have lower impedance (or resistance) passing through an inductor, while higher frequency signals will
have higher impedance passing through an inductor. This means that in our calculator, above, the higher the frequency you enter, the higher the impedance will be. And the lower the
frequency you enter, the lower the impedance will be. The same
effect that the frequency of the signal has, the inductance of the inductor has as well. The higher the inductance of the inductor, the higher the impedance. Conversely, the lower the
inductance,
the lower the impedance.
