Which of the following works on torque on the current carrying conductor placed in magnetic field ?
Correct answer: D. all of the above
- A. galvanometer
- B. ammeter
- C. voltmeter
- D. all of the above
Explanation
A moving-coil galvanometer produces torque when current-carrying conductors lie in a magnetic field. An ammeter and voltmeter are practical modifications of this mechanism, so all three use the same torque principle.
