The calculators below find the reactance of
capacitors and inductors at a specific AC frequency.
Capacitive Reactance Calculator (XC = 1 / (2pfC)):
Inductive Reactance Calculator (XL = 2pfL):
= 1 / (2 * pi * f * C), where f is the frequency and C is the capacitance in Farads
= 2 * pi * f * L, where L is the inductance in Henrys
See the technical data section
