156A Galvanometer is a very sensitive instrument. 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.
