AIIMS 2008 Physics Electric Circuits Assertion Reason Question

Type: Assertion Reason-numerical-Medium-Class 12

Assertion: In the following circuit, emf is 2 V and internal resistance of the cell is 1 Ω and R = 1 Ω, then reading of the voltmeter is 1 V.

Reason: V=E−IRV = E - IR where E=2E = 2 V, I=2/2=1I = 2/2 = 1 A.
