Moving Coil Galvanometer, Ammeter & Voltmeter

A galvanometer has resistance G and range Vg. How much resistance is required to read voltage up to V volt?

Show answer and solution

Answer: (c)

Full-scale current $I_g = \frac{V_g}{G}$ ; for range $V$ : $V = I_g(G + R)$ .
$R = \frac{V}{I_g} - G = \frac{VG}{V_g} - G$
$R = G\left(\frac{V}{V_g} - 1\right)$
So the answer is (c).
