MCQ
To convert an $AC$ generator into $DC$ generator :
  • ✓
    Split $-$ ring type commutator must be used.
  • B
    Slip rings and brushes must be used.
  • C
    A stronger magnetic field has to be used.
  • D
    A rectangular wire loop has to be used.
✓

Answer

Correct option: A.
Split $-$ ring type commutator must be used.
$AC$ generator has slip rings while the $DC$ generator has a split ring type commutator. To convert an $AC$ generator into $DC$ generator the split ring type commutator with which unidirectional current is obtained.
