Kirchhoff's Laws & Measuring Instruments

If only 5%5\% of the total current is to be passed through galvanometer of resistance G, then the resistance of the shunt will be

Show answer and solution

Answer: (c)

  1. S=IgGI−IgS = \frac{I_g G}{I - I_g} for a shunt across the galvanometer.
  2. Ig=0.05I⇒S=0.05G0.95=G19I_g = 0.05I \Rightarrow S = \frac{0.05G}{0.95} = \frac{G}{19}
  3. So the answer is (c) G19\frac{G}{19}.
