Question

The generator shown in Fig. 1 is rewired as a self-excited shunt DC generator and Radj adjusted to 10 Ω and generator speed is set at 1600 RPM. Ignoring the effects of armature reaction, answer the following questions:

If the generator is supplying 40 A to a load, what would be its terminal voltage in volts? (Answer in 2 decimal places). Note that 120V is your E_A.

What would be the total electrical losses in watts incurred by the generator in the question above?
