A DC machine is operated as a generator. The machine is connected as a shunt generator, with a brush
voltage drop of 2 volts. The armature resistance is 0.20 andthe shunt field winding resistance is 200.
The induced voltage is 220 V and the armature current is 40 amps. The rotational losses are 100 watts. Determine:
b) The net input power, i.e. the power from the machine that is used to rotate the generator rotor in watts.
Enter the answer in watts, i.e.,1.8 KW enter your answer as 1800
