A stand alone engine driven synchronous generator is feeding a partly inductive load. A capacitor is now connected across the load to completely nullify the inductive current. For this operating condition. (A) the field current and fuel input have to be reduced (B) the field current and fuel input have to be increased (C) the field current has to be increased and fuel input left unaltered (D) the field current has to be reduced and fuel input left unaltered
