Inductive Reactance Calculator
Calculate the reactance of an inductor at a given AC frequency — its opposition to alternating current — using XL = 2π × f × L.
Formula: XL = 2π × f × L
About Inductive Reactance Calculator
Inductive Reactance Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate the reactance of an inductor at a given AC frequency — its opposition to alternating current — using XL = 2π × f × L.
The calculation uses the standard formula XL = 2π × f × L and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
Inductive reactance rises with frequency, which is why inductors pass DC freely but block high-frequency signals in filter circuits.
