To convert an AC generator into DC generator
- split-ring type commutator must be used
- slip rings and brushes must be used
- a stronger magnetic field has to be used
- a rectangular wire loop has to 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.
The correct option is A.
