Operating torques in analogue instruments are_______________?
Correct answer: C. deflecting, control and damping
- A. deflecting and control
- B. deflecting and damping
- C. deflecting, control and damping
- D. vibration and balancing
Explanation
An analogue instrument needs deflecting torque to produce movement, controlling torque to establish the final position, and damping torque to prevent oscillations. Therefore, all three operating torques are required.
