A phase shifting transformer is used in conjunction with_______________?
Correct answer: B. Drysdale potentiometer
- A. D.C. potentiometer
- B. Drysdale potentiometer
- C. A.C. co-ordinate potentiometer
- D. Crompton potentiometer
Explanation
A phase-shifting transformer is associated with the Drysdale AC potentiometer, where it provides the required adjustable phase displacement. A DC potentiometer does not require phase shifting.
