When electric current is passed, electrons move from:
Option (a) high potential to low potential.
Why do electric currents move from a higher potential to a lower potential?
An electric current is defined to be the movement of positive charges. In reality, it is the electrons that do the moving. This happens because , an electric field appears inside conductors when when you complete the circuit. The electrons, in good conductors, are nearly free and begin to move under the influence of the electric field, from lower potential to higher potential. The “current” , by convention, therefore “moves” from higher potential to lower potential.
