Describe the working of an AC generator ...

Describe the working of an AC generator with the help of a labelled circuit diagram. What changes must be made in the arrangement to convert it into a DC generator ?

Text Solution

Verified by Experts

To convert an AC generator into DC generator, a split ring commutator should be used in the place of slip rings. This helps is producing unidirectional , i.e., direct current.
