Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : For measuring the potential difference across a resistance of , the voltmeter with resistance
will be preferred over voltmeter with resistance
.
Reason R : Voltmeter with higher resistance will draw smaller current than voltmeter with lower resistance.
In the light of the above statements, choose the most appropriate answer from the options given below.
Both and are correct and is the correct explanation of

To measure the potential difference between two point, voltmeter is used. But this voltmeter should be with higher resistance so that it cannot draw any current.
Now to measure the potential difference across voltmeter of
is much better than
voltmeter.
