Current Electricity Charging Discharging Of Capacitors Question 190
Question: A galvanometer of $ 100,\Omega $ resistance gives full scale deflection when 10 mA of current is passed. To convert it into 10 A range ammeter, the resistance of the shunt required will be
[MP PMT 1985]
Options:
A) $ -10,\Omega $
B) $ 1,\Omega $
C) $ 0.1,\Omega $
D) $ 0.01,\Omega $
Show Answer
Answer:
Correct Answer: C
Solution:
$ S=\frac{i _{g}G}{i-i _{g}}=\frac{100\times 0.01}{(10-0.01)}=\frac{1}{10}=0.1\Omega $
