JEE Mains · Physics · STD 12 - 4. Moving charges and magnetism
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 \(A\) is not correct but \(R\) is correct
- B Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\)
- C Both \(A\) and \(R\) are correct but \(R\) is not the correct explanation of \(A\)
- D \(A\) is correct but \(R\) is not correct
