Correct option is A
The correct answer is: (a) Infinite resistance Explanation: An ideal voltmeter should have infinite resistance to ensure it doesn’t draw any current from the circuit, allowing accurate potential difference measurement across components.
Information Booster:
· High resistance prevents current diversion through the voltmeter.
· Real voltmeters have very high but finite resistance.
· Connected in parallel with the element.
· It measures voltage or potential difference.
