A) 50 V range with \[10\,k\Omega \] resistance in series
B) 10 V range with \[200\,k\Omega \] resistance in series
C) 10 mA range with \[1\,\Omega \] resistance in parallel
D) 10 mA range with \[0.1\,\Omega \] resistance in parallel
Correct Answer: B
Solution :
To convert a galvanometer into an ammeter, a shunt \[S=\frac{{{I}_{g}}}{I-{{I}_{g}}}G\] is connected in parallel with it. To convert a galvanometer into a voltmeter, a resistance \[R=\frac{V}{{{I}_{g}}}-G\] is connected in series with it.
