Kirchhoff's Laws & Measuring Instruments

A galvanometer of resistance 100 Ω100\ \Omega gives full scale deflection for a current of 1 mA. It is converted into an ammeter of range 0−10 A0 - 10\text{ A}. The shunt required is:

Show answer and solution

Answer: (a)

  1. S=IgGI−IgS = \frac{I_g G}{I - I_g}
  2. S=10−3×10010−0.001=0.19.999≈0.01 ΩS = \frac{10^{-3} \times 100}{10 - 0.001} = \frac{0.1}{9.999} \approx 0.01\ \Omega
  3. So the answer is (a) 0.01 Ω0.01\ \Omega.
