Question

why the electrons flow in the conductor.​

Answer 1

Answer:

Conductors have plenty of free electrons i.e electrons that are not bound to a nucleus. These free electrons have enough kinetic energy to escape from their atoms and move around on their own in the conductor but they don’t have enough energy to escape from the surface of the conductor itself, unless they are provided with the energy required to do so.

Answer 2

Answer:

When a positive charged object is placed near a conductor electrons are attracted the object. 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.
