The resistance of an ideal ammeter is
The resistance of an ideal ammeter is zero.
Helping Concept
Working of ammeter: The ammeter is always connected in series in electronic circuits, if the ammeter has resistance then it will disturb the circuit current so that way the ideal ammeter has zero resistance.
Therefore, the correct option is (C).
