The sensitivity of a moving coil galvanometer can be increased by decreasing |
magnetic field area of the coil number of turns of the coil restoring couple per unit twist of suspension wire |
restoring couple per unit twist of suspension wire |
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. |
