how long does it take for a fruit to pruduce electricity?

Answer 1

How you can see for yourself how fruit can make electricity.
Materials Needed

* 2 lemons
* 3 copper wires
* 2 large paper clips
* 2 pennies
* a digital clock
* scissors
* knife
Instructions 2. First, attach one of the paperclips to a wire.
3. Then attach a penny to a second wire.
4. Attach another penny to one end of the third wire, and a paperclip to the other end.
5. Squeeze and roll two lemons to loosen the pulp inside.
6. Make two small cuts in the skins of both lemons an inch or so apart.
7. Put the paper clip that is attached to the wire and the penny into one of the cuts until you get to the juicy part of the lemon.
8. Stick the penny into a hole in the other lemon.
9. Put the other paper clip into the second hole of the lemon with the penny.
10. Then put the last penny into the last open hole.
11. Connect the free ends of the wires to the terminals of the digital clock.
12. Watch how the lemons make enough electricity to turn the clock on.
13. Here's how this lemon battery works. There's a chemical reaction between the steel in the paper clip and the lemon juice. There's also a chemical reaction between the copper in the penny and the lemon juice. These two chemical reactions push electrons through the wires.
14. Because the two metals are different, the electrons get pushed harder in one direction than the other. If the metals were the same, the push would be equal and no electrons would flow. The electrons flow in one direction around in a circle and then come back to the lemon battery. While they flow through the clock, they make it work. This flow is called electric current.
It will also work with an apple.

Answer 2

Your question doesn't really make sense... fruits don't produce electricity, unless you mean the cell potential. Every cell in plants and animals has a cell potential, which means that there is a difference in charge between the inside and the outside of the cell. This is because there are different concentrations of charged ions inside versus outside the cell. The difference in charge can be measured with a voltmeter; it is usually on the order of -70 millivolts. Every cell has this difference in charge from the time is is formed (by division of a previous cell into daughter cells), and continues to maintain it throughout its life.

Answer 3

Well, if it just sits there... hmm, you know, I don't think fruit are responsible for much of the world's electricity production.

If you were to burn the fruit to boil water and produce steam, like they do in electrical plants- no time at all.
