In capacitive circuit current leads or lags

WebWhen current leads the voltage (or voltage lags behind the current), the power factor of the circuit is called 'Leading'. When the circuit is capacitive, the pf is leading. Capacitive loads such as Synchronous condensers, capacitor banks etc draw leading current. Such circuits have leading power factor. WebSuppose a capacitor and an inductor are both connected across an alternating voltage supply (i.e., connected in parallel), then the same voltage sends a current through each. …
