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.
