# NEET Physics Current Electricity Questions Solved

PMT - 1999

A voltmeter has a resistance of G ohms and range V volts. The value of resistance used in series to convert it into a voltmeter of range nV volts is

(1) nG

(2) $\left(n-1\right)G$

(3) $\frac{G}{n}$

(4) $\frac{G}{\left(n-1\right)}$

(2) Suppose resistance R is connected in series with voltmeter as shown.

By Ohm's law

${i}_{g}.R=\left(n-1\right)V$

$R=\left(n-1\right)G$ (where ${i}_{g}=\frac{V}{G}$
