Reactance calculator

Calculate capacitive reactance and inductive reactance with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use capacitive reactance and inductive reactance to compare changes to your inputs. The method and limits below explain the scope.

Calculation method

Calculation method

Capacitive reactance (Ω)

If b = 0, report Open circuit. Otherwise 1/(2 × π × a × b/10^6).

Inductive reactance (Ω)

2 × π × a × c/1000.
