    ASSERTION: In the given circuit, emf is 2V and internal resistance of the cells is 10 and \[R=1\Omega \], then reading of the voltmeter is IV.
    REASON: \[V=R-1R\] where E = 2V, \[I=\frac{2}{2}=1A\]
     

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.
