Kirchhoff's Laws & Measuring Instruments

In conversion of moving coil galvanometer into an ammeter of required range, the resistance of ammeter, so formed is

[ $S =$ shunt and $G =$ resistance of galvanometer]

Show answer and solution

Answer: (b)

The shunt $S$ is connected in parallel with the galvanometer $G$ .
Ammeter resistance $= \frac{SG}{S + G}$
So the answer is (b).
