Generating an Electric Current
Question: “Are there other household items that can be used to replicate the electrochemical properties of “The Baghdad Battery”?
Hypothesis: Using household items to mimic the parts of “The Baghdad Battery” can create similar results.
• An electrolyte solution that is safe to handle will need to be found
• Materials for electrodes will need to be found and/or created
• A small voltage object to test the current will be needed (light bulb, etc)
• To mimic the battery, safe household items need to be used for the electrolyte. For this experiment, it will be lemons.
• Create enough current to light a bulb. Lemons do not create enough current (although they do create small currents at 1.5 volts) to light an incandescent bulb (unless multiple lemons are used in a serial connection).
Description of Method or Procedure: To describe the procedure used, we will quote from the following website: www.energyquest.ca.gov... :
“What do you need?
1. 18-gauge copper wire (smaller gauge will work too, but 18-gauge is stiffer)
2. Wire clippers
3. Steel paper clip (Some people find that a 2-inch strip of zinc works better)
4. Sheet of coarse sandpaper
6. Help from an older friend or an adult
What To Do?
1. Have your older friend or an adult strip 2 inches of insulation off the copper wire. Clip the 2 inches of bare wire with the clippers.
2. Straighten out the paper clip and cut about 2 inches of the straightened steel wire, or use a 2-inch piece or strip of zinc.
3. Use sandpaper to smooth any rough spots on the ends of the wire and paper clip or piece of zinc.
4. Squeeze the lemon gently with your hands. But don't rupture the lemon's skin. Rolling it on a table with a little pressure works great.
5. Push the pieces of the paper clip and the wire into the lemon so they are as close together as you can get them without touching.”
