The direction of an electric currentis 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. Electrons would actually move through the wires in the opposite direction.

What is the direction of current flow in a conductor?
Also, many experiments have revealed that it is free electrons in a conductor that flows. Negatively charged electrons move from the negative terminal to the positive terminal. This is the direction of the actual current flow. In terms of circuit analysis, we normally consider the direction of electric current from positive to negative.
How does current flow through a battery?
These freed electrons are attracted to the positive ions created by the positive terminal of the cell. The net result is a massive movement of electrons from the negative terminal of the battery to the positive terminal. This is how current flows in wires and cables and most electronic components.
Does current flow in a circuit?
I would like to suggest that current does NOT flow! It is charge carriers (electrons, ions, protons and other charged subatomic species, or holes) that flow in response to an electric field, electrical potential gradient, or voltage.
Does current flow from positive to negative?
Therefore, the charge is said to flow from positive to negative. This is called conventional current. But in reality, an electric current is nothing but the flow of electrons. Electrons are negatively charged particles and are attracted towards the positive charge.
