Vedclass · Answer

(B) An ideal ammeter is designed to measure the current in a circuit without affecting the current flow. To ensure that the current remains unchanged,an ideal ammeter must have zero resistance. If the resistance were not zero,it would cause a voltage drop across the ammeter,thereby altering the total current in the circuit.
