Direction of Direct Current (DC) Electricity
By convention, the direction of direct current (DC) electricity in a DC circuit goes from the positive (+) terminal of the source towards the negative (−). The historical background started with designating the electric charges as plus and minus and then naming the ends of a battery as positive (+) and negative (−).

The direction of the electric current | IOPSpark
Scientists agree to use a convention which shows the direction of the electric charge flow (the current) in a circuit as being from the positive terminal of the battery towards the negative terminal. This is in the opposite direction to the actual flow of electrons–the most common moving charged particles in circuits.

Electric Current – definition, equation, types and direction
Hence observing the terminals of a battery one can identify the direction of current in a mesh. In above circuit, the positive terminal of the battery is on the left side and hence the current flows clockwise. But this method cannot be applied to a complicated circuit having more than two or three loops.

20.5: Alternating Current versus Direct Current
Alternating Current Most of the examples dealt with so far, and particularly those utilizing batteries, have constant voltage sources. Once the current is established, it is thus also a constant. Direct current (DC) is the flow of electric charge in only one direction. It is ...
In which direction does current flow in an electric circuit?
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. Electrons would actually move through the wires in the opposite direction.

For some electrodes, though not in this example, positive ions, instead of negative ions, complete the circuit by flowing away from the negative terminal. As shown in the figure, the direction of current flow is opposite to the direction of electron flow. The battery continues to discharge until one of the electrodes is used up [3, p. 226].
Understanding the Basics: A Simple Battery Diagram Explained
A battery diagram is a graphical representation of a basic battery circuit. It helps to illustrate how a battery is connected in a circuit and how the current flows within the circuit. By understanding the basic concept of a battery diagram, one can have a clear visual understanding of how a battery functions in an electrical circuit.
