Into every potato put a copper and a zinc electrode. Although the electrodes should be placed on the same side, avoid letting them come into contact. These two dissimilar metals will function as electrodes, triggering an electrochemical process required to create electricity.
4. Link the potatoes
Join the copper electrode in one potato to the zinc electrode in the other using alligator clips. This link is very important as it completes the circuit and lets electricity flow.
5. Attach Your Charger
Cut one end of a USB charger so that the wires inside are visible. Usually, you will notice a red and a black wire; they match positive and negative charges accordingly.
Using additional alligator clips—red wire to copper and black to zinc—connect the exposed wires to the electrodes in the potatoes.
6. Turn on charging.
Once everything is linked, your potato battery should be able—albeit very slowly—generate enough power to charge your phone. A discernible charge might need the voltage from many potatoes.
In conclusion
One amazing approach to investigate renewable energy sources straight from your kitchen is running potatoes to create power. Although fast charging your phone is not expected, this experiment is a great approach to grasp fundamental electrical concepts and the possibilities of alternate energy sources. It's also a fantastic discussion starter on how common items may be used for power.
