Do free electrons travel to region of higher potential or lower potential ?
Do free electrons travel to region of higher potential or lower potential ?
No. There is negative charge on free electrons. The free electrons experience electrostatic force in a direction opposite to the direction of electric field. The direction of electric field is always from higher potential to lower. Hence, free electrons will move from lower potential to higher potential.
