$begingroup$ There is a convention for the technical direction of the current: positive current flows from the plus pole of a battery to the minus pole by convention. The microscopic details of conduction in a specific medium/conductor are a different thing. In some conductors, like metals, it is actually electrons that flow.

Kirchhoff''s First Rule. Kirchhoff''s first rule (the junction rule) applies to the charge entering and leaving a junction (Figure (PageIndex{2})).As stated earlier, a junction, or node, is a connection of three or more wires. Current is the flow of charge, and charge is conserved; thus, whatever charge flows into the junction must flow out.
In such a case, with the capacitor now discharging, donating energy, that current must be in the direction in which it exits via the capacitor''s higher potential terminal, just like a battery. Note: Actually, it is possible for a resistor to donate energy to other parts of a circuit, in the form of noise current.
However, before the invention of this electron theory of current flow, the scientists of the 17th century arbitrarily decided that the electric current flows from positive potential to negative potential. This so-called conventional flow of current till today is accepted as the direction of electric current flow.
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. Key Terms. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
A convention for direction. 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 charges in metal wires ...
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 …
Then, if the polarity of this virtual battery is opposed to the 6V battery and its voltage is larger than 6V, you will get a current flow against the normal battery current flow given by the difference of battery voltages divided …
Note that the direction of current flow in Figure 2 is from positive to negative. The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move ...
The current I is in the direction of conventional current. Every battery has an associated potential difference: for instance, a 9-volt battery provides a potential difference of around 9 volts. This is the potential difference between the battery terminals when there is no current, and is known as the battery emf, (emf stands for
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 …
DC current flows in one direction only, so it does not fluctuate as AC current does: AC current is often used in devices that require high amounts of power, such as microwaves and hair dryers : DC current is often …
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.

The direction of current flow in any cell can be reversed by the application of a sufficiently large counter-potential. When a cell operates as a source of current (that is, as a galvanic cell), the cell reaction is a spontaneous process. Since, as the cell reaction proceeds, electrons move through a potential difference in the external circuit, the reaction releases energy in the cell''s ...
Why do we define the direction of current as the positive charge flow direction? Benjamin Franklin (pictured in Figure 2.1.2.1 ) began experimenting with the phenomenon of electricity in 1746. In 1752 he performed his famous kite experiment proving that lightning is a form of electricity by capturing charge from storm clouds in a leyden jar (an early form of an electrical …
