Reactance Calculator

The calculators below find the reactance of capacitors and inductors at a specific AC frequency.

Capacitive Reactance Calculator (XC = 1 / (2pfC)):

XC = ?

Inductive Reactance Calculator (XL = 2pfL):

XL = ?


Capacitive reactance:

XC = 1 / (2 * pi * f * C), where f is the frequency and C is the capacitance in Farads

Inductive reactance:

XL = 2 * pi * f * L, where L is the inductance in Henrys

See the technical data section for more details
