To determine which fruits will generate enough electricity to light a light bulb and to see which fruit will light a bulb the longest.
Can fruits produce electricity to light a light bulb?
I think that citrus fruit can produce electricity but not enough to light a light bulb of 1.2 volts.
My experiment was to see of you could produce electricity from fruits. I got electricity out of grapefruits, lemons, limes, and bananas. It took me about an hour or two to get this experiment but to get all the typing and to decorate my board it will probably take me about 2 hours.
I have also found out that certain fruits contain substances such as ascorbic acid, citric acid, and NADH.
The fruit with the citric acid is the type of fruit I used. citric acid seemed to produce a lot of electricity but not enough to light a light bulb.
in order to power a light bulb you will need both voltage and current. When connect fruit in parallel, it gives you a higher current. Connect the fruit in series arrangement it increase the voltage.

The grapefruit with the most volts will not produce light
One lemon does not light a bulb. When 1 and 2 are in series it contains .45 volts.
