The sensitivity of a moving coil galvanometer can be increased by decreasing
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → restoring couple per unit twist of suspension wire
Correct statement:
☀ restoring couple per unit twist of suspension wire
Explanation: The sensitivity of a moving coil galvanometer increases if the restoring torque (restoring couple per unit twist) of the suspension wire is decreased. This allows the coil to deflect more for a given current.
