Question

how does we can convert a galvanometer into a ammeter?

Answer 1

Since Galvanometer is a very sensitive instrument therefore it can’t measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.


SOME ADDITIONAL INFORMATION....
To convert a galvanometer into a voltmeter you connect a suitable high resistance in series with the coil of the galvanometer.
