Question

The net resistance of a voltmeter of a should be high to ensure

(1) It does not get overheated

(2) It does not draw excessive current

(3)  It can measure large potential difference

(4) It does not appreciably change the potential difference to measure

Answer 1

Correct option (4) It does not appreciably change the potential difference to measure

Explanation:

Net resistance of a voltmeter should be high so that it doesn’t appreciably change the potential difference to measure.
