Magnetic Effects Of Current Question 461
Question: A moving coil galvanometer has a resistance of $ 900\Omega $ . In order to send only 10% of the main current through this galvanometer, the resistance of the required shunt is
Options:
A) $ 0.9\Omega $
B) $ 100\Omega $
C) $ 405\Omega $
D) $ 90\Omega $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ I_{g}=0.1I,,I_{s}=0.9I;,S=I_{g},R_{g}/I_{s} $ $ =0.1\times 900/0.9=100\Omega $
