Questions
The net resistance of a voltmeter should be large to ensure that
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
detailed solution
Correct option is D
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.Talk to our academic expert!
