Electrons flow in a wire when there is
A)an imbalance of charges in the wire.
B)more potential energy at one end of the wire than the other end.
C)a potential difference across its ends.

Electrons flow in a wire when there is a potential difference across its ends. This is because the potential difference creates an electric field that causes the electrons to move from the negative end to the positive end of the wire, thus creating an electric current. The imbalance of charges and more potential energy at one end of the wire are not sufficient to cause electrons to flow in a wire.
