The net resistance of a voltmeter should be large to ensure that

Options

A. It does not get overheated
B. It does not draw excessive current
C. It can measure large potential difference
D. It does not appreciably change the potential difference to be measured

Answer

D

Explanation

(d) The resistance of voltmeter is too high, so that it draws negligible current from the circuit,hence potential drop in the external circuit is also negligible.
