Inductor reactance is the opposition that an inductor provides to the change of current in an AC circuit. It is a form of impedance caused by the inductance of the coil or circuit element. The reactance is proportional to both the frequency of the alternating current and the inductance of the coil.
The formula for calculating inductive reactance is:
X_L = 2 * π * f * L
Where:
Inductive reactance is an important consideration in the design of AC circuits because it determines how much the inductor resists changes in current. It is especially relevant in the analysis and design of filters, transformers, and other AC equipment.
