Question 12. [10] A separately excited generator develops a no-load e.m.f of 150 V at an armature speed of 20 rev/s and a flux per pole of 0.10 Wb. Determine the generated e.m.f when, P 6 a) The speed increases to 25 rev/s and the pole flux remains unchanged. b) The speed remains at 20 rev/s and the pole flux is decreased to 0.08 Wb, and c) The speed increases to 24 rev/s and the pole flux is decreased to 0.07 Wb.
