The only difference between construction of D.C generator and A.C generator is that of_______________?
Correct answer: C. commutator
- A. carbon brushes
- B. coil
- C. commutator
- D. magnetic field
Explanation
A DC generator uses a split-ring commutator to rectify the internally generated AC, whereas an AC generator generally uses slip rings to obtain alternating output. The armature, field system and brushes may otherwise have similar construction.
