Question

what is the resistance of an ideal volmeter and an ammeter
​

Answer 1

Answer:

Consequently an ideal voltmeter will have infinite resistance. An ammeter is connected in series with the circuit to be measured. The ideal ammeter will have zero resistance so as not to disturb the circuit.

Explanation:

A voltmeter is used to measure the potential difference across the two points of a circuit. The voltmeter is connected in parallel across those two points to measure potential difference. The potential difference measured by voltmeter will be accurate if no current is drawn by voltmeter. Resistance of this voltmeter is infinite. An ammeter is used to measure the current in the circuit. An ammeter is connected in a series in the circuit. For ideal ammeters, there is zero resistance.
