An inductive component is said to have a lagging power factor because the current lags the voltage.
A capacitive component is said to have a leading power factor because the current leads the voltage.
With reference to the following diagram, when current lags voltage Q is positive,
thus is positive.
With this interpretation:
a.a lagging PF, Q is positive,
b.a leading PF, Q is negative.
