When do electrons move for the flow of charges in a conducting metallic wire?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. Only if there is a difference of electric pressure.

  • When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor.
  • Electrons will move toward the positive side.
  • The "electrical pressure" due to the difference in voltage between the positive and negative terminals of a battery causes the charge (electrons) to move from the positive terminal to the negative terminal.
