The sensitivity of a moving coil galvanometer depends on
Answer & explanation
Correct answer: option 3
The sensitivity of a moving coil galvanometer depends upon: (a) The value of n, i.e., number of turns. (b) The value of B, i.e., the intensity of the magnetic field. (c) torsional rigidity.
Current sensitivity =$\frac{nBA}{k}$
where K is constant of torsional rigidity.
