A current of \(10^{-7} A\) produces 50 division deflection in a galvanometer. The figure of merit would be :
- A \(50 \times 10^{-7} A / div\)
- B \(50 \times 10^7 A / div\)
- C \(2 \times 10^{-9} A / div\)
- D \(2 \times 10^{-8} A / div\)
Answer & Solution
Correct Answer
(C) \(2 \times 10^{-9} A / div\)
Step-by-step Solution
Detailed explanation
\( k = \frac{I}{\theta} \) \( k = \frac{10^{-7} A}{50 \text{ div}} \) \( k = 2 \times 10^{-9} A / \text{ div} \)
