Question: The resistance of 1 A ammeter is $ 0.018,\Omega $ . To convert it into 10 A ammeter, the shunt resistance required will be
[MP PET 1982]
Options:
A) $ 0.18,\Omega $
B) $ 0.0018,\Omega $
C) $ 0.002,\Omega $
D) $ 0.12,\Omega $
Show Answer
Answer:
Correct Answer: C
Solution:
$ S=\frac{i _{g}G}{(i-i _{g})} $
$ =\frac{1\times 0.018}{10-1}=\frac{0.018}{9}=0.002\Omega $
