Current Electricity Charging Discharging Of Capacitors Question 267
Question: A galvanometer has 30 divisions and a sensitivity 16 $ \mu A/\text{div}\text{.} $ It can be converted into a voltmeter to read 3 V by connecting
[Kerala PMT 2005]
Options:
A) Resistance nearly 6 $ k,\Omega $ in series
B) $ 6,k,\Omega $ in parallel
C) $ 500,\Omega $ in series
D) It cannot be converted
Show Answer
Answer:
Correct Answer: A
Solution:
$ (R+G),i _{g}=V $
Therefore $ (R+G)=\frac{V}{i _{g}} $
$ =\frac{3}{30\times 16\times {{10}^{-6}}}=6.25k\Omega $
$ \
Therefore $ Value of $ R $ is nearly equal to $ 6k\Omega $ This is connected in series in a voltmeter.
