Current Electricity Charging Discharging Of Capacitors Question 219
Question: A moving coil galvanometer has a resistance of $ 50,\Omega $ and gives full scale deflection for 10 mA. How could it be converted into an ammeter with a full scale deflection for 1A
[MP PMT 1996]
Options:
A) $ 50/99,\Omega $ in series
B) $ 50/99,\Omega $ in parallel
C) $ 0.01,\Omega $ in series
D) $ 0.01,\Omega $ in parallel
Show Answer
Answer:
Correct Answer: B
Solution:
$ S=\frac{i _{g}\times G}{i-i _{g}}=\frac{10\times {{10}^{-3}}\times 50}{1-{{10}^{-3}}\times 10}=\frac{50}{99}\Omega $ in parallel.
