Q)

A multi range current meter can be constructed by using a galvanometer circuit as shown in figure . We want a current meter that can measure $10\;mA,100\;mA$ and $1\;A$ using a galvanometer of resistance $10 \Omega$ and that produces maximum deflection for current $1\;mA$ Find $S_1,S_2$ and $S_3$ that have to be used

$\begin{array}{1 1} S_1= 11 \Omega ; S_2= 1 \Omega ; S_3= 0.11\Omega \\ S_1= 1.1 \Omega ; S_2= 0.1 \Omega ; S_3= 0.11\Omega \\ S_1= 1.1 \Omega ; S_2= 0.1 \Omega ; S_3= 0.011\Omega \\ S_1= 11 \Omega ; S_2= 10 \Omega ; S_3= 0.011\Omega \end{array} $
