Q.
The ammeter has range $1\ ampere$ without shunt. The range can be varied by using different shunt resistances. The graph between shunt resistance and range will have the nature
A) $P$
B) $Q$
C) $R$
D) $S$
Explanation
(b) To make range $n$ times, the galvanometer resistance should be $G/n,$ where $G$ is initial resistance
