Potato Battery Explained
Batteries have 3 parts 1.An anode which is the negative terminal 2.A cathode which is the positive terminal 3.The electrolyte which is a compound that ionizes when dissolved in a solvent The chemical reactions in a battery cause the electrons to build up at the anode. This results in a chemical difference between the anode and the cathode. This difference is an unstable buildup of the electrons. The electrons want to arrange themselves so that there is no longer a difference. But they have to do this in a specific way. The electrons repel each other and try to go to the place with the fewer electrons. In a battery the only place to go is a cathode. But, the electrolyte keeps the electrons from going straight from the anode to the cathode inside the battery. When the circuit is closed the electrons will be able to get to the cathode. In the picture above, the electrons go through the wire, lighting the light bulb along the way. However, these electrochemical processes change the chemica...
