Most sensitive galvanometer is_____________?
Correct answer: D. spot ballistic galvanometer
- A. elastic galvanometer
- B. vibration galvanometer
- C. Duddlb galvanometer
- D. spot ballistic galvanometer
Explanation
A spot ballistic galvanometer uses optical spot deflection and is designed to detect very small quantities of charge, giving very high sensitivity. The optical method avoids the limited scale resolution of an ordinary pointer.
