The sensitivity of moving coil galvanometer is inversely proportional to

The sensitivity of moving coil galvanometer is inversely proportional to
  1. current it measures.
  2. number of turns in the coil.
  3. magnetic induction of horse shoe magnet
  4. torsional constant

Solution

$\mathrm{C} \theta=\mathrm{n} \mathrm{A} \mathrm{B} \mathrm{i}$ Sensitivity $=\frac{\theta}{i}=\frac{n A B}{C}$
