Free QuoteThis apparent contradiction arises from historical conventions in electrical engineering, which defined current flow based on the movement of positive charges. In reality, the internal chemical reactions within the battery generate an excess of electrons at the negative terminal.
In a battery, chemical reactions occur within the cell, causing a flow of electrons from the negative terminal (cathode) to the positive terminal (anode). This movement of electrons creates an electric current that can be harnessed for various applications.
The terminal marked negative is the source of electrons. When a battery is connected to an external electric load, those negatively charged electrons flow through the circuit and reach to the positive terminal, thus cause a redox reaction by attracting positively charged ions, cations.
The positive terminal, often marked with a plus sign (+) or a longer protrusion, represents the battery's source of positive charge. On the other hand, the negative terminal, marked with a minus sign (-) or a shorter protrusion, represents the battery's source of negative charge.
If electrons make one side of the battery negative, then the other side is lacking those electrons and wants them. Because the positive terminal is lacking those electrons it has a much more positive voltage. It likely has a lot more protons (which are positive) than the negative side of the battery.
Now the chemical process within the battery is "triggered" and these electrons are again "moved" to the negative pole of the battery. So, now you have a circuit the electrons go around. So electrons do flow out of the negative side. The positive sign indicates this side is positively charged compared to the negative side.
