A) number of turns in the coils
B) are of the coil
C) magnetic field
D) couple per unit twist of the suspension
Correct Answer: D
Solution :
For moving coil galvanometer \[C\theta =niBA\]where C = Couple per twist of the suspension \[\theta =\] deflection of galvanometer \[\frac{\theta }{i}=\frac{nBA}{C}\] Sensitivity of galvanometer \[=\frac{nBA}{C}\] \[\therefore \]To increase the sensitivity of galvanometer, value of C should be decreased.
