Options

(A)

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).

(B)

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

(C)

Assertion (A) is true, but Reason (R) is false.

Marking scheme

1. $1 mark$

Hint

$Recall the definition of electric potential difference and the direction of electron flow in a conductor.$

Quick oral answer

$The assertion is incorrect because electrons move from higher potential to lower potential in a conductor. The reason is correct because a dry cell does maintain electric potential difference across the ends of a conductor.$

Common mistakes

1. $Incorrectly assuming electrons move from lower to higher potential$

Analysis and explanation

The assertion is incorrect because electrons move from higher potential to lower potential in a conductor, not the other way around. The reason is correct because a dry cell does maintain electric potential difference across the ends of a conductor.

Interesting facts

$The concept of electric potential difference is crucial in understanding the flow of electric current in a circuit.$
