Electrical Machines Two generators G1 and G2 are to be operated in parallel to deliver a total current of 60 A. Generator one has a terminal voltage of 280 V on no load and 240 V when supplying 40 A current. Similarly the second generator has a voltage of 300 V when on no load and 240 V when supplying of 50 A of current. The output voltage of each generator will be 256.4 V. 238.2 V. 271.7 V. 240 V. 256.4 V. 238.2 V. 271.7 V. 240 V. ANSWER DOWNLOAD EXAMIANS APP
