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.
Answer: (A) A is not correct but R is correct
A voltmeter should draw as little current as possible, so the $4000\ \Omega$ one disturbs the circuit less and is preferred: A is not correct. R is correct.
