Detailed Solution

The above statement is false.
The total resistance would be high if the resistance of the ammeter were also high. This would decrease the amount of current flowing through the circuit. Hence, to keep away from the change of current flowing in a circuit. Therefore, the resistance of an ammeter should be as small as 0.
The correct statement would be that an ammeter's resistance should be as small as zero.
