A moving coil galvanometer, having a resistance 
, produces full scale deflection when a current 
flows through it. This galvanometer can be converted into (i) an ammeter of range 0 to 
by connecting a shunt resistance RA to it and (ii) in-to a voltmeter of range 0 to 
by connecting a series resistance 
to it. Then,

When galvanometer is used an ammeter shunt is used in parallel with galvanometer.
When galvanometer is used as a voltmeter, resistance is used in series with galvanometer.
