How does a capacitor improve power factor?
Show More Ask Question

1 Answer

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 by leading current angle.total power =VI cos(phase angle)

Phase angle becomes low and the value of cos(phase angle) is increase and hence power also max.

Answer :  Capacitors generate reactive power instead of that drawn from source which is required by inductive loads.so it reduce the reactive current which is drawn from source to be drawn from capacitor.This control in Electric bills cost.
