Capacitive Reactance

Capacitive Reactance (Xc) is a measure of the opposition of capacitance. Xc varies with the frequency of the electrical signal. Reactance is measured in ohms, symbol ohm.


Xc= reactance

f = frequency

C = capacitance 

Xc and f



Xc is large at low frequencies

Xc is small at high frequencies.
