Question
A galvanometer of 50 ohms gives full scale deflection with 2 mA current. To convert it into an ammeter of range 10 A, the shunt resistance should be:
Correct Answer
Option C is the correct answer.
Detailed Explanation
Rs = IgRg/(I-Ig) = (0.002)(50)/9.998 = 0.01 ohms.
Hint
Rs = IgRg/(I-Ig) = (0.002)(50)/9.998 = 0.01 ohms.
