Question

Problem 21

Answer 1

Given information

An ideal ammeter have zero resistance and an ideal voltmeter have infinite resistance.

Step-by-step explanation

Step 1.

Ammeter is used to measure current  and it is always connected in the series of the circuit. if ammeter have zero resistance only then it can measure correct value of current in the circuit , as the total resistance of the circuit will not change . Also there is no voltage drop across the ammeter.
