engineering recuitment UPCL AE (E&M) 2021 Mock Test Electrical Machines Alternator and Synchronous Motors
The synchronous motor fed from an infinite bus is delivering the half full load. If an increase in its field current causes an increase in armature current, then the motor will:
1
deliver reactive power Q and active power P
2
absorb P and Q
3
absorb P and deliver Q
4
deliver P and absorb Q
