The nameplate of a dc generator indicates that it will produce an output voltage of 24 V
Question:
The nameplate of a dc generator indicates that it will produce an output voltage of 24 V dc when operated at a speed of 1200 r/min. By what factor must the number of armature turns be changed such that, for the same field-flux per pole, the generator will produce an output voltage of 18 V dc at a speed of 1400 r/min?
