Define capacitive reactance. Write its SI units.

Text Solution

Verified by Experts

Capacitive reactance of a capacitor is the opposition offered by it for flow of a current through it. 1 Capacitive reactance `X_(C) =1/(C omega)` , where w is the angular frequency of current supply. SI unit of capacitive reactance is ohm `(Omega)`.
