In D.C. generators, current to the external circuit from armature is given through_____________?
Correct answer: A. commutator
- A. commutator
- B. solid connection
- C. slip rings
- D. none of above
Explanation
The armature generates alternating emf, and the commutator mechanically rectifies it so that current delivered to the external circuit is unidirectional. Slip rings would transfer alternating current and are used in alternators rather than ordinary D.C. generators.
