Current Electricity Charging Discharging Of Capacitors Question 236

Question: If only 2% of the main current is to be passed through a galvanometer of resistance G, then the resistance of shunt will be

[MP PMT/PET 1998]

Options:

A) $ \frac{G}{50} $

B) $ \frac{G}{49} $

C) $ 50,G $

D) $ 49,G $

Show Answer

Answer:

Correct Answer: B

Solution:

$ i _{g}=2% $ of $ i=\frac{i}{50} $

Therefore $ S=\frac{G}{(n-1)}=\frac{G}{(50-1)}=\frac{G}{49} $
