Question

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 $600\Omega$, the voltmeter with resistance $1000\Omega$ will be preferred over voltmeter with resistance $4000\Omega$.
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.

• A. Both $A$ and $R$ are correct but $R$ is not the correct explanation of $A$
• B. Both $A$ and $R$ are correct and $R$ is the correct explanation of $A$
• C. A is not correct but $R$ is correct
• D. A is correct but $R$ is not correct

Answer 1

Answer: (C)

Error of voltmeter decreases with increase in its resistance.
