Vedclass · Answer

(B) galvanometer can be converted into an ammeter by connecting a very low resistance,known as a shunt resistance $(S)$,in parallel with the galvanometer coil.$1$. The purpose of the shunt resistance is to bypass the majority of the current through it,protecting the sensitive galvanometer coil from damage due to high current.$2$. If $G$ is the resistance of the galvanometer and $I_g$ is the current for full-scale deflection,then the shunt resistance $S$ required to measure a total current $I$ is given by the formula: $S = \frac{I_g G}{I - I_g}$.$3$. The effective resistance of the resulting ammeter is $R_{eq} = \frac{G \cdot S}{G + S}$,which is very low,ensuring that the ammeter does not significantly alter the current in the circuit it is measuring.
