Question

why do the free electrons in a metal wire flowing by themselvs not cquse any current flow in tha wire​

Answer 1

Answer:

The electrons move in random directions and the net effect is that there is no effective movement of charge in one direction. ... When a potential is applied, the electric field exerts a force on the electrons in one direction. All the electrons will move in one direction causing the current.

Answer 2

Answer:

Explanation:

When there is no potential difference across the ends of a wire, there is no net electric field inside the wire across the ends. ... When a potential is applied, the electric field exerts a force on the electrons in one direction. All the electrons will move in one direction causing the curren
