In case of galvanometer the circuit does not have any resistor so it detectos or measures the current flowing through it ,while in an ammeter we are connecting a resistor called shunt parallel to galvanometer .As we know in parallel connection of resistors the current is divided .My question is that ,an ammeter have to find only the current flowing through it not the whole current comming from soure as half of the current is passing through the shunt resistor ,if this is the case there should be no difference bw a galvanometer and an ammeter?

Answer:
A galvanometer can be converted into voltmeter by connecting a high resistance called multiplier in series to the galvanometer. This equation gives the value of resistance R, which connected in series to the galvanometer, is converted into a voltmeter of range 0 – V volts
