Moving coil Galvanometer

Question

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

Easy

A

it does not get overheated
B

it draws excessive current
C

it can measure large potential difference
D

it does not appreciably change the potential difference to be measured

Solution

The resistance of voltmeter is too high, so that it draws negligible current from the circuit, hence does not change the potential drop to be measured.
