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

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 EA.

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