Answer:
Metallic conductor contains free electrons,which are charge particles. Any charge particle will always try to move towards the lower potential energy region if they are free to move.

Answer:
Metallic conductor contains free electrons, which are charge particles. Any charge particle will always try to move towards the lower potential energy region if they are free to move. Since the electrons are almost free in metal, they moves towards lower potential energy region as there is a potential difference. This movement of electrons is the Electric Current of the circuit.
