Question: A galvanometer is used in laboratory for detecting the null point in electrical experiments. If, on passing a current of $6 \mathrm{~mA}$ it produces a deflection of $2^{\circ}$, its figure of merit is close to:
$3 \times 10^{-3} \mathrm{~A} /$ div.
$333^{\circ} \mathrm{A} /$ div.
$6 \times 10^{-3} \mathrm{~A} /$ div.
$666^{\circ} \mathrm{A} / \mathrm{div}$.
Correct Option: 1
Solution:
