Question

Assertion (A): Electrons move from lower potential to higher potential in a conductor. Reason (R): A dry cell maintains electric potential difference across the ends of a conductor.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Answer 1

The Correct Option is B

Step 1: Analyze the Assertion (A)
Assertion (A): Electrons move from lower potential to higher potential in a conductor.
✔️ This statement is true. In an electric circuit, electrons (which are negatively charged) move from the negative terminal (lower electric potential) to the positive terminal (higher electric potential) of a power source such as a cell or battery.

Step 2: Analyze the Reason (R)
Reason (R): A dry cell maintains electric potential difference across the ends of a conductor.
✔️ This statement is also true. A dry cell creates a constant potential difference (voltage) between its terminals, which causes current (flow of electrons) to move through the conductor.

Step 3: Check if Reason (R) explains Assertion (A)
❌ Although both statements are true, Reason (R) does not directly explain why electrons move from lower to higher potential. The direction of electron flow is due to the nature of electric charge, not just the existence of a potential difference.

Final Answer:
Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of Assertion (A).
