Question
Define capacitor reactance. Write its S.I units.
Solution
Capacitor reactance is the resistance offered by a capacitor when it is connected to an electric circuit. It is given by
`X_C=1/(omegaC)`
where
ω = Angular frequency of the source
C = Capacitance of the capacitor
The SI unit of capacitor reactance is ohm (Ω).
