Question

The commercial efficiency of a shunt generator is maximum when its variable loss equals

Answer 1

Hey!! ☺

Here is your answer

_______________________

it is found that e.m.f. in D.C. Generators 909 rather it will ... In the case of shunt generators, D.C. Generators 927 Total loss = armature copper loss + Wc = Ia 2 ... current corresponding to maximum efficiency is given by the relation ..... If the pole span or coil pitch is equal to the pole pitch (as in the case..
