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:
Options
A 0.1 ohms
B 0.2 ohms
C 0.01 ohms
Correct Answer
D 0.02 ohms
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.
