In majority of instruments damping is provided by______________?
Correct answer: C. eddy currents
- A. fluid friction
- B. spring
- C. eddy currents
- D. all of the above
Explanation
Eddy-current damping is widely used because it provides effective damping without physical contact or added friction at the moving system. Fluid friction is used in some instruments, but it is not the usual answer for the majority.
