Answer 1

❣️Hi there ❣️

Look at the attachment !

If we replace the slip rings of an A.C generator by a commutator ,then it will become a D.C generator.Thus ,in a D.C generator ,a split ring type commutator is used .When the two half rings of commutator are connected to the two ends of the generator coil, then one carbon brush is at all times in contact with the coil arm moving down in the magnetic field while the other carbon brush always remains in contact with the coil arm moving up in the magnetic field.Due to this , the current in outer circuit always flows in one direction.So , it is direct circuit .
Now , look at the figure.

Thanks ☺️

Answer 2

We have just studied an A. C generator which produces alternate current. In order to obtain direct current a D. C generator is used. Acctually, If we replace the slip rings of an A. C generator by a commutator then it will become a

D. C generator. Thus D. C generator a split ring type commutator is used (Like the one used in an electric motor )

The only difference between a D. C generator and A. C generator is in the ways the two ends of the generator coil are linked to the outer circuit.
