Analyzing +4 | -1

Assertion: EMF of battery decreases with time.
Reason: Internal resistance increases with time.

View answer and explanation

Correct option: B

If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion

Option B is correct because both Assertion and Reason are true, but the Reason is not a correct explanation of the Assertion. The EMF decreases due to chemical changes, and the internal resistance increases due to electrolyte depletion.
