The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that "Current between two points in an electrical circuit always flows from higher potential to lower potential." - This is a fundamental principle in electricity. Current (conventional current) is defined as the flow of positive charge. In a circuit, positive charges move from a region of higher electric potential (positive terminal) to a region of lower electric potential (negative terminal). ### Step 2: Understand the Reason The reason states that "During charging of a battery, current inside the battery flows from the negative terminal to the positive terminal." - When charging a battery, the external circuit is connected in such a way that the current flows into the positive terminal of the battery and out of the negative terminal. This is indeed true. However, the statement in the reason is misleading because it implies that the current flows from negative to positive inside the battery during normal operation, which is not the case when the battery is discharging. ### Step 3: Analyze the Relationship Between Assertion and Reason - The assertion is correct as it aligns with the basic principle of current flow in circuits. - The reason is partially correct but misleading in its wording. It does not accurately describe the flow of current in a typical discharging scenario, where current flows from positive to negative externally. ### Conclusion The assertion is true, but the reason is false. Therefore, the correct answer is that the assertion is correct, but the reason is incorrect. ### Final Answer The assertion is true, and the reason is false. Thus, the correct option is D. ---
