A.C. series motor as compared to D.C. series motor has__________?
Correct answer: E. all of the above
- A. smaller brush width
- B. less number of field turns
- C. more number of armature turns
- D. less air gap
- E. all of the above
Explanation
An AC series motor uses fewer field turns, more armature turns, a smaller air gap, and narrower brushes than a comparable DC series motor to reduce reactance, losses, and sparking. Hence all the listed modifications apply.
