# Inductive Reactance The impedance of an air wound coil is given by the following formula: Xl = 2 * pi * f * L Where Xl is the inductive reactance in ohms, f is the frequency in hertz and L the inductance of the coil in Henrys. An inductor wound on an iron or ferrite core will have a different value.
