Description : In a DC generator the windings of interpoles are connected : (A) in series with main field winding, to create a pole,of same polarity as the main pole ahead in the direction of rotation. (B) in series with main field winding, to create a pole of opposite polarity as the main pole ahead in the direction of ... in the direction of rotation. (D) in series with the armature winding, to create a pole of opposite polarity as the main pole ahead in the direction of rotation.
