Current Electricity Charging Discharging Of Capacitors Question 288
Question: A 100 ohm galvanometer gives full scale deflection at 10 mA. How much shunt is required to read 100 mA
[MP PET 2002]
Options:
A) 11.11 ohm
B) 9.9 ohm
C) 1.1 ohm
D) 4.4 ohm
Show Answer
Answer:
Correct Answer: A
Solution:
$ i _{g}=i\frac{S}{G+S} $
Therefore $ 10\times {{10}^{-3}}=\frac{S}{100+S}\times 100\times {{10}^{-3}} $
$ 90\ S=1000\Rightarrow $
$ S=\frac{1000}{90}=11.11\ \Omega $ .
