Solution

The correct option is C split ring type commutator
To convert AC generator to DC generator split ring type commutator must be used.

An electric generator works on the principle of electromagnetic induction. Electromagnetic induction is the phenomenon in which an emf is induced in the coil if there is any change in the magnetic flux linked to the coil. In a generator, a coil is rotated in a magnetic field, due to which magnetic flux linked with the coil changes and induces an emf. The current generated constantly changes diretion and is hencec called AC. DC is a type of current which has a single direction. Hence, to convert AC ot DC, split rings are used.
