Assetion : In the following circuit emf is `2 V` and internal resistance of the cell is `1 Omega` and `R = 1 Omega`, then reading of the voltmeter is `1 V`. Reason : `V = E - ir` where `E = 2 v, i= (2)/(2) = 1 A` and `R = 1 Omega` A. If both the assertion and reason are true and reason is a true explanation of the assertion.B. If both the assertion and reason are true but the reason is not the correct explanation of assertion.C. If the assertion and reason are falseD. If both the assertion and reason are false. |

Answer» Correct Answer - A (a) Here, `E = 2 V, 1 = 2//2 = 1 A` and `r = 1 Omega` Therefore, `V = E - ir = 2 - 1 xx 1 = 1 V` |
