A galvanometer is used in laboratory for detecting the null point in electrical experiments. If, on passing a current of 6 mA it produces a deflection of 2o, its figure of merit is close to :

Multiple Choice Options

  • A 6 ×\times 10–3 A/div
  • B 666o A/div
  • C 3 ×\times 10–3 A/div
  • D 333o A/div

Step-by-Step Verified Solution

figure of merit = Iθ{I \over \theta }

= 6×10−32{{6 \times {{10}^{ - 3}}} \over 2}

= 3 ×\times 10–3 A/div
