For a D.C. generator when the number of poles and the number of armature conductors is fixed, then which winding will give the higher e.m.f___________ ?
Correct answer: B. Wave winding
- A. Lap winding
- B. Wave winding
- C. Either of A. and B. above
- D. Depends on other features of design
Explanation
Generated e.m.f. is inversely related to the number of parallel paths. Wave winding normally has only two parallel paths, whereas lap winding has approximately one path per pole, so wave winding gives the higher e.m.f.

The more specific you are, the faster it gets fixed. A source beats an opinion.
