Two 220 V dc generator each having linear external characteristic operate in parallel. One machine has terminal voltage of 270 V. On no load and 220 V at a load current of 35 A while the other has a voltage of 280 V at no load and 220 V 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 the condition?
