The electricity doesnrsquot actuallycome from the potato, rather the water and electrolytes in the spud allow electrons from the copper to move to the zinc, creating small electric currents. In this reaction, the copper is being reduced thus, the shed of electrons and the zinc is being oxidized. The way a potato battery works is on-premise, the same way all electrochemical batteries store and release electricity. If it STILL doesn’t light up you may not have enough voltage (we didn’t), cut the potatoes in half and add in more coins and nails to make the circuit bigger. We needed six potato halves to light up our LED light. How many did you need? Did you try quartering them? What happened? This reaction leaves behind a shortage of electrons at the copper electrode, which is the key reason why electrons keep flowing from the zinc to the copper electrode. The battery keeps running until it either runs out of protons if there is not a lot of acid present, or the zinc electrode is "eaten up" and completely dissolved into ions. The overall net reaction in a potato battery can be summarized as: Click This Link.
