The flow of current is always in what direction

The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.

Explanation:

Electrons always flow in opposite directions. The direction of an electric current is by convention the direction in which a positive charge would move. Electric current flows from higher electric potential to lower electric potential.

Explanation:
