What determines the direction of flow of electrons when two charged conductors are joined by a metallic wire?

Solution

When two charged conductors are joined by a metallic wire, the direction of the flow of electrons is determined by the potential of the conductor.
The electrons flow from the lower potential region to the higher potential region.
Hence, the potential of the conductor determines the direction of the flow of electrons when two charged conductors are joined by a metallic wire.
