Kirchhoff's Laws & Measuring Instruments

Two identical galvanometers are converted into an ammeter and into milliammeter. For the same current, the value of shunt of the ammeter as compared to that of milliammeter is

Show answer and solution

Answer: (a)

$S = \frac{I_g G}{I - I_g}$ , so for the same $G$ and $I_g$ a larger range $I$ needs a smaller shunt.
An ammeter has a much larger range than a milliammeter.
So the answer is (a) less.
