Question

Potential difference is applied across the ends of a conductor. Choose the correct statement.

• A. Electrons move from higher potential to lower potential.
• B. Electrons move from lower potential to higher potential.
• C. Protons move from lower potential to higher potential.
• D. Protons move from higher potential to lower potential.

Answer 1

The correct option is B Electrons move from lower potential to higher potential.

When a wire is connected between two points and the potential difference between the two points is non- zero, current flows from the higher potential to the lower potential. As electrons flows in the opposite direction to the current, they move from the lower to higher potential.
