Question

Assertion:In the part of a circuit shown in figure, given that `V_(b) gt V_(a)`. The current should flow from b to a.
Reason: Direction of current inside a battry is always from negative terminal to positive terminal.
A. If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
C. If Assertion is true, but the Reason is false.
D. If Assertion is false but the Reason is true.

Answer 1

Correct Answer - C
If current flows from `a` to `bm`, then equation will become
`V_a-ir-E=V_b` or `V_a-V_b=E+ir`
so, `V_a-V_b` is always positive. Hence `V_a` is always greater than `V_b`.
