Question:-
A separately excited dc machine is coupled to a 50Hz, three-phase, 4-pole induction machine as shown in the figure. The dc machine is energized first and the machines rotate at 1600 rpm. Subsequently the induction machine is also connected to a 50Hz, three-phase source, the phase sequence being consistent with the direction of rotation. In steady state,

Option (A)
Both machines act as generators
Option (B)
The dc machine acts as a generator, and the induction machine acts as a motor
Option(C)
The dc machine acts as a motor, and the induction machine acts as a generator
Option(D)
Both machines act as motors
