A galvanometer is used in laboratory for detecting the null point in electrical experiments. If, on passing a current of $6 m A$ it produces a deflection of $2^{\circ}$ , its figure of merit is close to :

Options:

Answer:

Solution:

Current sensitivity $= \frac{1}{θ} = \frac{6 \times 1 0 ^{- 3}}{2} = 3 \times 1 0^{- 3}$
