The has energy come from somewhere. In an electrochemical battery, it comes from chemical reactions with the electrodes, which consume the electrode material.
- VLM 12y agoIts basically one of these: http://en.wikipedia.org/wiki/Zinc%E2%80%93carbon_battery http://en.wikipedia.org/wiki/Zinc%E2%80%93carbon_battery The carbon rod never corrodes. If you want to be picky its more of a zinc-manganese battery with a carbon rod as a non-corrosive wire but whatever.
- Elrac 12y agoAs VLM explains a bit better, I was talking about only one of the two electrodes. The other one, the anode, would of course be made from zinc (or some other metal) and end up breaking down to provide that energy. I was just explaining why the battery might not need two electrodes breaking down.
