Current Electricity Charging Discharging Of Capacitors Question 272

Question: In a circuit 5 percent of total current passes through a galvanometer. If resistance of the galvanometer is G then value of the shunt is

[MP PET 2001]

Options:

A) 19 G

B) 20 G

C) $ \frac{G}{20} $

D) $ \frac{G}{19} $

Show Answer

Answer:

Correct Answer: D

Solution:

$ \frac{i _{g}}{i}=\frac{S}{G+S} $

Therefore $ \frac{5}{100}=\frac{S}{G+S} $

Therefore $ S=\frac{G}{19} $
