An ammeter should have negligible resistance because it is used to measure the current flowing through a circuit. If the ammeter has a significant resistance, it will affect the current being measured and give inaccurate readings. By having negligible resistance, the ammeter will have minimal impact on the circuit and provide more accurate measurements of the current flowing through it.

An ammeter is a device used to measure electric current. It is connected in series with the circuit in which the current is to be measured. The ideal ammeter has zero resistance, so that it does not affect the current flowing in the circuit.
If an ammeter had non-negligible resistance, it would introduce an additional resistance into the circuit. This would cause the current to decrease, and the ammeter would not give an accurate reading.
In practice, it is impossible to construct an ammeter with zero resistance. However, ammeters are designed with very low resistance, so that the error introduced by their resistance is negligible.
