The potato doesn't actually produce any electricity. Rather, it's the metals inserted into the potato slowly dissolving and releasing electrons. A single potato battery only produces about half a volt. It would take several potatoes connected together to power even a single LED, much less an entire light bulb. 1 апр. 2021 г.
Can you use potatoes to make electricity?
The potato battery is a type of electrochemical battery, or cell. Certain metals (zinc in the demonstration below) experience a chemical reaction with the acids inside of the potato. This chemical reaction creates the electrical energy that can power a small device like an LED light or clock.
Why LED Cannot be lit with one potato?
The potato is not a source of electricity by itself. Potato batteries require two different metal electrodes with different electrical qualities to work. The most common materials are zinc and copper. The acids in the potato react with the metals, creating an electron imbalance at each electrode.
