The resistance of an ammeter is typically very low, ideally 0 ohms. This is because an ammeter is designed to measure the current flowing through a circuit without affecting the circuit itself. The lower the resistance of the ammeter, the more accurately it can measure the current without causing any significant voltage drop. However, in practical ammeters, there is always some internal resistance, which is typically very small, in the order of milliohms.
