Vedclass · Answer

(A) An ideal ammeter is designed to measure the current flowing through a circuit without affecting the circuit's parameters. To ensure that the ammeter does not change the current it is measuring,it must have zero resistance. If the resistance were non-zero,it would cause a voltage drop across the ammeter,thereby altering the total current in the circuit. Therefore,the resistance of an ideal ammeter is $0 \ \Omega$.
