Kirchhoff's Laws & Measuring Instruments

Two identical galvanometers are converted into voltmeter and millivoltmeter. As compared to the series resistance of voltmeter, the series resistance of millivoltmeter will be

Show answer and solution

Answer: (c)

Series resistance $R = \frac{V}{I_g} - G$ , so it grows with the range $V$ .
A millivoltmeter has a much smaller range than a voltmeter, so it needs a smaller series resistance.
So the answer is (c) less.
