Damping of the Ballistic galvanometer is made small to_______________?
Correct answer: A. get first deflection large
- A. get first deflection large
- B. make the system oscillatory
- C. make the system critically damped
- D. get minimum overshoot
Explanation
A ballistic galvanometer measures the first throw produced by a charge, so small damping allows a larger initial deflection and preserves the charge-deflection relationship. Heavy damping would reduce the first throw and spoil sensitivity.
