Engine: Electricity

1. A In a complete revolution of the armature, the current flow direction within the armature winding does not reverse, and the current flow direction in the external load also does not reverse.
2. B In a complete revolution of the armature, the current flow direction within the armature winding does not reverse, whereas the current flow direction in the external load does reverse.
3. C In a complete revolution of the armature, the current flow direction within the armature winding does reverse, whereas the current flow direction in the external load does not reverse.
4. D In a complete revolution of the armature, the current flow direction within the armature winding does reverse, and the current flow direction in the external load also does reverse.
