Which of the following components of a D.C, generator plays vital role for providing direct current of a D.C. generator ?
Correct answer: B. Commutator
- A. Dummy coils
- B. Commutator
- C. Eye bolt
- D. Equilizer rings
Explanation
The commutator mechanically rectifies the alternating emf induced in the armature conductors, delivering unidirectional current at the external terminals. Dummy coils, eyebolts and equalizer rings do not perform this rectifying function.
