A galvanometer has a deflection of 25 divisions for a current of 0.1 A flowing through it. Then the current sensitivity of the galvanometer is
  1. $25 \mathrm{div} / \mathrm{A}$
  2. $250 \operatorname{div} / \mathrm{A}$
  3. $2.5 \mathrm{div} / \mathrm{A}$
  4. $0.25 \mathrm{div} / \mathrm{A}$

Solution

Current sensitivity, $\mathrm{I}_{\mathrm{S}}=\frac{\mathrm{NBA}}{\mathrm{k}}$ $=\frac{25}{0.1}=250 \mathrm{div} / \mathrm{A}$
