Discussion
Assertion (A): Interpoles are connected in series with the armature.
Reason (R): Their correction must follow the load current automatically.
Select the correct option.
Answer: D
Correct answer: Both A and R are true, and R is the correct explanation of A
Both are true and the reason gives the mechanism. The reactance voltage is proportional to the armature current, so the correction must be proportional to it too. Connecting the interpoles in series with the armature makes their flux follow the load automatically, at every load and at every moment, with nothing to adjust.
