But what happens inside the battery?
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.
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.
Does the current flow backwards inside a battery?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode. According to Ohm's law, this means that the current is proportional to the electric field, which says that current flows from a positive to negative electric potential.
How does a battery charge and discharge?
Charging and Discharging Processes: Current flow reverses during the charging process. A battery is recharged by applying external voltage, prompting the current to flow in the opposite direction. This process restores the original chemical compositions at the electrodes, allowing the battery to be used again.
