Inductive Impedance Formula

The inductive impedance formula relates the impedance of an inductor to its inductance and the frequency of the alternating current passing through it.

The formula for the inductive impedance is given by:

ZL = jωL

● ZL is the impedance of the inductor in ohms
j is the imaginary unit, which is the square root of -1
ω is the angular frequency of the AC current in radians per second
L is the inductance of the inductor in henries


The inductive impedance formula shows that the impedance of an inductor is proportional to the frequency of the AC current and the inductance of the inductor. The higher the frequency or the inductance of the inductor, the higher the impedance will be.
