Explanation:

A shunt is a device that creates a low-resistance path for electric current, to allow it to pass around another point in the circuit.

Two uses of shunt:

i The range of ammeter reading can be extended by connecting a shunt resistance to it.

ii The shunt is used in the galvanometer for measuring the large current

A moving-coil galvanometer can be converted into an ammeter by reducing its effective resistance by connecting a parallel low resistance S across the coil. Such a parallel low resistance is called a shunt since it shunts a part of the current around the coil. ... This gives the required resistance of the shunt.
