Detailed Solution

Explanation: Ammeter's resistance should be low as much as possible and it is connected in series in a circuit so total resistance of circuit should not be affected.

If we want to increase range of ammeter, we have to decrease the resistance which is possible by adding a shunt in parallel to it.
