Detailed Solution

The above statement is False.
We know that an ammeter is used to measure the current flow in a circuit. It is always connected in a series of the electric circuit, the current flowing through which is to be measured. An ammeter is always connected in series because, in a series arrangement, the current flowing through all circuit components is the same.
Since the current remains the same, the resistance has to be low. On the other hand, if the resistance of an ammeter is high, there will be significant alterations in the current to be measured.
Therefore the correct statement would be that the resistance of an ammeter must be low.
