DC Generators Quiz 2

The ideal condition for the voltage regulation in DC generators is that it _______________ with the load current.

• remains constant

• increases

• decreases

• remains zero

The drop in terminal voltage is caused by the loss in voltage due to ________________.

• armature reaction

• commutator reaction

• field poles reaction

• brushes reaction

It is the type of DC generator whose field magnets are energized from an independent external source of dc current.

• separately-excited dc generator

• long-shunt compound wound dc generator

• series wound dc generator

• self-excited dc generator

These types of dc generators are those whose field magnets are energized by the current produced by the generators themselves.
