In a D.C. generator the number of mechanical degrees and electrical degrees will be the same when____________?
Correct answer: D. number of poles is 2
- A. r.p.m. is more than 300
- B. r.p.m. is less than 300
- C. number of poles is 4
- D. number of poles is 2
Explanation
Electrical angle equals mechanical angle multiplied by P/2, where P is the number of poles. The two angles are equal only for a two-pole generator.
