Of ammeter and voltmeter whose resistance is greater and why?

Text Solution

Verified by Experts

The resistance of voltmeter is greater than that of ammeter .Voltmeter is connected in parallel with the main the main circuit and has higher resistance so that it does not change the current in the main circuit.
