Current Electricity Charging Discharging Of Capacitors Question 200
Question: $ 100,mA $ current gives a full scale deflection in a galvanometer of $ 2,\Omega $ resistance. The resistance connected with the galvanometer to convert it into a voltmeter to measure $ 5,V $ is
[MNR 1994; UPSEAT 2000]
Options:
A) $ 98,\Omega $
B) $ 52,\Omega $
C) $ 50,\Omega $
D) $ 48,\Omega $
Show Answer
Answer:
Correct Answer: D
Solution:
$ R=\frac{V}{i _{g}}-G=\frac{5}{100/10^{3}}-2 $
$ =\frac{5000}{100}-2=48\Omega $
