A galvanometer is used in laboratory for detecting the null point in electrical experiments. If, on passing a current of 6mA it produces a deflection of 2°, its figure of merit is close to :
  1. 333° A/div
  2. 6×10-3A/div
  3.  666° A/div.
  4. 3×10-3A/div

Solution

Current sensitivity =1θ=6×10-32=3×10-3
