re help how to construct home built battery for rd grade sci report in article c qui cf spk hp com borowski spk hp com don t borowski writes dean anneser anneser pwa b uucp wrote my yr old son has signed up to do a science report on batteries i was wondering if anyone could provide me with some information as to how to construct a home built battery in my grade school days i remember snip i haven t been following this so i m sorry if somebody already mentioned this but you could grab a lemon i think potatoes work too but i m not sure a strip of copper and a strip of zinc i think you can get the metal in a hardware store or hobby shop maybe stick the strips in the lemon so they don t touch and you ll get a measurable voltage not a lot but hey it s a lemon as i recall we had to hook something like ten of these things to get an appreciable amount of current because of the mondo internal resistance but if you just need a demo you might get it to run a tiny fan or something mark s underwood ee student university of kentucky lab assistant boyd hall microlab a tiny little division of uk library microlabs e mail msunde mik uky edu
