Physics - Current Electricity Question with Solution | TestHub

A moving coil galvanometer, having a resistance$\mathrm{G},$produces full scale deflection when a current${\mathrm{I}}_G$flows through it. This galvanometer can be converted into (i) an ammeter of range 0 to${\mathrm{I}}_{\mathrm{o}}\left({\mathrm{I}}_0>{\mathrm{I}}_{\mathrm{g}}\right)$by connecting a shunt resistance${\mathrm{R}}_{\mathrm{A}}$to it and (ii) into a voltmeter of range 0 to$\mathrm{V}\left(\mathrm{V}=\mathrm{G}{\mathrm{I}}_0\right)$by connecting a series resistance${\mathrm{R}}_{\mathrm{V}}$to it. Then,
