In D.C. generators, the brushes on commutator remain in contact with conductors which_________________?
Correct answer: C. lie under interpolar region
- A. lie under south pole
- B. lie under north pole
- C. lie under interpolar region
- D. are farthest from the poles
Explanation
Commutation occurs while a coil is short-circuited by a brush, and the corresponding conductors lie in the interpolar or neutral region where the main flux is approximately zero. This reduces the emf induced during commutation.
