- 1In a DC generator, the armature rotates and the field system is stationary; in an AC generator, the armature is always stationary and the field system is missing.
- 2In a standard commercial AC generator, the field system rotates and the armature is stationary; whereas in a DC generator, the armature rotates and the field system is stationary.✓
- 3In a DC generator, there is no armature winding present.
- 4In a DC generator, the magnetic field exists alternately without any field poles.
Correct answer
In a standard commercial AC generator, the field system rotates and the armature is stationary; whereas in a DC generator, the armature rotates and the field system is stationary.
