Detailed Solution

The above statement is True.
The commutator on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction. The brushes ride on the commutator and make good electrical connections between a generator and the load. These brushes are made up of carbon. Thus, brushes play an essential role in a DC generator.
