How does a capacitor improve power factor?

Description :

How does a capacitor improve power factor?

Answer :

Every circuit are usually more inductive than capacitive.it means that the current lags by voltage at small angle.hence we have to compensate this situation so we use Capacitor then this lag is compensate ... angle becomes low and the value of cos(phase angle) is increase and hence power also max.
