D.C. series generator

D.C. shunt generator

D.C. Long shunt compound generator

D.C. short shunt compound generator

field winding open

residual magnetism available in the field poles

generator running at the rated speed

generator runs in the correct direction

The best method of stopping a DC shunt generator is to open the field circuit switch

The existence of residual magnetism is must in a self-excited DC generator

As the shunt field current increases, the induced voltage also increases initially

As the speed of the DC generator increases, the induced voltage also increases up to a certain extent.
