Question 349 of 380

A galvanometer is used in laboratory for detecting the null point in electrical experiments. If, on passing a current of 6mA6mA it produces a deflection of 2∘2^{\circ}, its figure of merit is close to :

Show answer and solution

Answer: (D) 3×10−3A/div3\times {10}^{-3}A/div

Current sensitivity =1θ=6×10−32=3×10−3=\dfrac{1}{\theta }=\dfrac{6\times {10}^{-3}}{2}=3\times {10}^{-3}
