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:
Correct Option: 1
Solution:
Figure of Merit $=C=\frac{i}{\theta}$
$=\mathrm{C}=\frac{6 \times 10^{-3}}{2}=3 \times 10^{-3} \mathrm{Am}^{2}$
