Current Electricity Charging Discharging Of Capacitors Question 197
Question: In order to pass 10% of main current through a moving coil galvanometer of 99 ohm, the resistance of the required shunt is
[MP PET 1990, 99; MP PMT 1994; RPET 2001; KCET 2003, 05]
Options:
A) $ 9.9,\Omega $
B) $ 10,\Omega $
C) $ 11,\Omega $
D) $ 9,\Omega $
Show Answer
Answer:
Correct Answer: C
Solution:
Shunt resistances $ S=\frac{i _{g}G}{(i-i _{g})}=\frac{10\times 99}{(100-10)}=11\Omega $
