Q150 / 160 · AP EAMCET 2023 (16 May Shift 2) · Physics

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

  • A
    $25 \mathrm{div} / \mathrm{A}$
  • Correct answer
    B
    $250 \operatorname{div} / \mathrm{A}$
  • C
    $2.5 \mathrm{div} / \mathrm{A}$
  • D
    $0.25 \mathrm{div} / \mathrm{A}$

Solution

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

Hence, the correct answer is option: 'B'.
