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.

Analysis & 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.
