lemon battery experiment

we wanted to find out how a battery works so we did the famous lemon battery experiment 

and this is what we found.

• 1 lemon =0.9 volts
• 3 lemons = 2.7volts and lit up and LED.

Here is a picture we have a cucumber, potato, lemon & banana giving 3.64 volts.

this is a link for a video about a lemon battery.
