Potato battery raw materials: 4 potatoes, 4 zinc sheets, 4 copper sheets, 1 small light bulb, and 8 wires.

1. Prepare the above materials, note that fresh potatoes are required.

2. Fix the wires on the copper and zinc sheets respectively.

3. Design the circuit diagram. The left and right sides of the light bulb are the positive and negative poles respectively.

4. Embed the copper and zinc sheets into the potatoes, and then connect the wires in sequence. The last two wires do not need to be connected.

5. Connect the last two wires to the small light bulb.

6. A small light bulb can light up.

Potato power generation mainly uses batteries made of electrodes made of potatoes and metal to provide power.

Potato power generation, this green, high-efficiency battery is made of zinc, copper electrodes and cooked potato slices. The potatoes provide the acid needed for the reaction, which enables the movement of electrons from copper to zinc, the copper and zinc poles of the battery coming from copper nails and galvanized nails respectively. Each potato can produce about 0.5 volts of voltage and about 0.2 milliamps of current.
