Kirchhoff's Laws & Measuring Instruments

A galvanometer of resistance $100\ \Omega$ gives full scale deflection for a current of 1 mA. It is converted into an ammeter of range $0 - 10\text{ A}$ . The shunt required is:

Show answer and solution

Answer: (a)

$S = \frac{I_g G}{I - I_g}$
$S = \frac{10^{-3} \times 100}{10 - 0.001} = \frac{0.1}{9.999} \approx 0.01\ \Omega$
So the answer is (a) $0.01\ \Omega$ .
