7. AC generator

 Armature rotates in between field magnets
 Whenever the armature rotates the slip rings comes
in contact with brush.
 While rotating the slip rings contact with the same
brush.
 Every time AC is produced in the armature coil.

9. DC generator

 Armature rotates between poles of the field magnet
 While the armature rotates the split rings always
comes in contact with brush.
 While completing each half rotation, the connection
between split rings and brush changes.
 Always DC is produced in the armature coil.
