It is desired to pass only 5% of the current through a galvanometer of resistance 95Omega . What shunt resistance should be connected across it ?

A moving coil galvanometer, having a resistance G, produces full scale deflection when a current Ig flows through it. This galvanometer can be converted into (i) An ammeter of range 0 to I_(0)(I_(0)gtI_(g)) by connecting a shunt resistance R_(A) to it and (ii) Into a voltmeter of range 0 to V(V=GI_(0)) by connecting a series resistance R_(V) to it.
