Question
A galvanometer of 50Ω gives full scale deflection with 2mA current. To convert it into ammeter of range 10 A, shunt resistance should be
Correct Answer
Option C is the correct answer.
Detailed Explanation
Shunt resistance S = (Ig × G)/(I - Ig) = (0.002 × 50)/(10 - 0.002) ≈ 0.01Ω.
Hint
Use the shunt formula: S = (Ig × G)/(I - Ig).
