Create a Lemon Battery

Dec 1, 2011 - Everyone here seems to believe that the energy comes out of the lemons. It does not. It comes from the reaction between Zinc on the nail and Copper on the penny. The lemon just act as electrolyte

Nov 20, 2011 - well you know what they say, when life gives you lemons, make a battery

Nov 13, 2011 - thanx it really works and it help me a lot in my schools projects................

Sep 22, 2011 - The point is that a lemon provides the circuit even with a huge internal ohmic resistance, thus the reported voltage value is correct only because the measrumement device doesn't need a sensible current to measure it and it does not allow the current to flow along the series. But the very time you inset a load on the series, allowing the current to flow along, the internal resistance lowers the available voltage for the load (i.e. the LED); thus actually the effective output voltage is smaller.

Jan 8, 2011 - nice demo ... i wander what current flows though a citric acid battery as the one build by you :-? ... if you do the measurment i would like to get a link :D

Jan 6, 2011 - Thanks. I'm doing that in class and i had no idea what is was. This explained itself so well! Thanks again!

Jan 5, 2011 - Thank you for this video! I have an urgent question: where did you buy the LED light?! I took an LED light out of a keychain light, and tried to connect it to my circuit, but it won't light up. Please respond! anyone else can respond too if you know! THANKS

Jan 2, 2011 - nice info. thanks a lot.

Oct 26, 2010 - my next science project

tomcwe Says:

Oct 25, 2010 - what if i connect multiple electrodes to a single lemon instead of cutting the lemon?

Aug 5, 2010 - v v nice Mr. Scienceonline, Thanks for sharing

americanforthewin Says:

Aug 5, 2010 - Why if there was enough voltage, more than an AA battery, did you have to add more lemons? Why was the current low or weak? What makes 1 battery beat 4 lemons? Thank you for your response.

Jul 29, 2010 - lol this is so funny but so cool LEMON POWERRR

brilliantstudent Says:

Jul 27, 2010 - Hello Will a LED work with a vinegar battery???

TheNeatron Says:

Jul 8, 2010 - um, isn't an battery two or more cells? so one lemon is equal two one cell so it cant be a battery you would require two lemons i think. am i right?

Jul 1, 2010 - i think i have to subscribe because this is so interesting!

Dec 29, 2009 - so wait... if lemons make electricity.. and there are cars that run with electricity, we could run those cars with that electricity instead of using and producing cars that run with gasoline.. that would be a great way of reducing CO2 in our air because we would also have to plant billions of lemon trees which would of course make photosynthesis.. that would be awesome let's do it!!!

WeedPatch71 Says:

Dec 28, 2009 - Normal lights (tungsten) require far more current then LEDs. So a normal light would require far more lemon's to light up.

Dec 23, 2009 - The position of the metals don´t matter. The calculator´s LCD and CMOS technologies use very little current. No special parts are necessary to power a calculator with lemons :-)
