Kirchhoff's Laws & Measuring Instruments

A galvanometer has resistance of $100\ \Omega$ and a current of 10 mA produces full scale deflection in it. The resistance to be connected in series, to get a voltmeter of range 50 volt is

Show answer and solution

Answer: (d)

Series resistance $R = \frac{V}{I_g} - G$ .
$R = \frac{50}{10 \times 10^{-3}} - 100 = 5000 - 100 = 4900\ \Omega$
So the answer is (d) $4900\ \Omega$ .
