Current Electricity Charging Discharging Of Capacitors Question 241
Question: A galvanometer has resistance of $ 7,\Omega $ and gives a full scale deflection for a current of 1.0 A. How will you convert it into a voltmeter of range 10 V
[MP PMT 1999]
Options:
A) $ 3,\Omega $ in series
B) $ 3,\Omega $ in parallel
C) $ 17,\Omega $ in series
D) $ 30,\Omega $ in series
Show Answer
Answer:
Correct Answer: A
Solution:
By connecting a series resistance $ R=\frac{V}{i _{g}}-G=\frac{10}{1}-7=3,\Omega $
