No, current flow in a battery does not move from positive to negative. Instead, the flow of electric current is conventionally described as moving from the positive terminal to the negative terminal. Electric current is defined as the flow of electric charge.
What is the difference between a positive charge and a negative charge?
While electrons, which carry negative charge, actually move from the negative side of a battery to the positive side, current is defined in terms of positive charge flow as conventional current describes the flow of hypothetical positive charge. Scientific consensus, especially in educational settings, further enforced current flow conventions.
Why does a battery have a negative charge?
This 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.
Why do electrons flow from negative to positive in a battery?
So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive. You might wonder why the electrons don't just flow back through the battery, until the charge changes enough to make the voltage zero.
What happens if a battery has a positive and negative side?
