Q6. Two 220 V d.c. generators each having linear external characteristics, operated in parallel. One machine has a terminal voltage of 270 V on no load and 220V at a load current of 35 A, while the other has a voltage of 280 V at no load and 220V at 50 A. Calculate the output current of each machine and the bus bar voltage when the total load is 60 A. what is the kW output of each machine under this condition. (16)
