उत्तर
As shown in the diagram the only change is that both the slip-rings of an A.C. generator are replaced by a split-ring (X-Y) (a ring split in two halves) which acts as a commutator or current-reverser.
A. C. Generator
D. C. Generator
The other parts in both are the same. By this device the current in the external circuit becomes unidirectional.
