Assertion:In the part of a circuit shown...


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.

Text Solution

Verified by Experts

The correct Answer is:
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`.
