Moving Coil Galvanometer, Ammeter & Voltmeter

The value of shunt resistance that allows $5\%$ of the main current through the galvanometer of $100\ \Omega$ is nearly

Show answer and solution

Answer: (b)

Galvanometer and shunt are in parallel: $I_gG = (I - I_g)S$ .
$I_g = 0.05I \Rightarrow S = \frac{0.05 \times 100}{0.95} \approx 5.26\ \Omega$
So the answer is (b) about 5 $\Omega$ .
