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
@ScHnitzLLlicious92 even a very tiny extremely low voltage LED needed 4 lemons to barely glow a little bit, in your case we will need a truck of lemons following us to supply enough lemon to run the power-eager car engine at 10kmph ~6mph
just to be clear, one drip of gasoline has more power than a box of fresh lemons
well you know what they say, when life gives you lemons, make a battery
thanx it really works and it help me a lot in my schools projects…………….
Very cool I can’t wait to try it
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.
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 
thank you very much. this video helped me a lot in our investigatory project.
im using this as my science project, but im giving you credit
Thanks. I’m doing that in class and i had no idea what is was. This explained itself so well! Thanks again!
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
could you start a car?
nice info. thanks a lot.
my next science project
what if i connect multiple electrodes to a single lemon instead of cutting the lemon?
v v nice Mr. Scienceonline, Thanks for sharing
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.
lol this is so funny but so cool
LEMON POWERRR
Hello
Will a LED work with a vinegar battery???
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?
i think i have to subscribe because this is so interesting!
kool
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!!!
Normal lights (tungsten) require far more current then LEDs. So a normal light would require far more lemon’s to light up.
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
