Composition structure of potato power generation
1, potato battery consists of zinc electrode, copper electrode and cooked potato chips, potatoes provide the acid needed for the reaction, and copper and zinc at the battery poles come from copper nails and galvanized nails.
2. A potato battery can generate a voltage of 0.5 volts and a current of 0.2 mA, and the surface of the cooked potato will have a coating, which is the key to the potato battery.
3. It is found that cooked potatoes have ten times as much electricity as uncooked potatoes, that is, the power generation capacity is increased by about ten times, and the power supply time is prolonged.
Method for producing potato power generation
1, cut the potato in half, dig a small hole in one half, keep the other one still, and put a proper amount of salt in the small hole, just right, not too full.
2. Then put toothpaste on the salt, let the toothpaste cover the salt, and mix and stir together.
3. Make two sharp sticks, which can be cut by ordinary branches. Make two 20 cm wires with wires and cut both ends of the line.
4. The other potato should be inserted with four holes, two in the middle and two outside.
5. Wait for about ten minutes, then tie the wool to a wire head, and connect the two wire heads, and the wool will burn.
