Lemon Battery

This World Could Run On Lemons


Lemon Battery's in Amps/Milliamps

1st:0.250 mA

2nd:0.104 mA

3rd:0.160 mA

4th:0.104 mA

5th:0.180 mA

D-Battery Current In Amps

1st:0.955 A

2nd:0.965 A

3rd:.962 A

Avg Lemon Current: 0.1592 mA

Avg D-Battery Current: 0.960 A


How many lemons would it take to equal the voltage of a D-Battery?


I think it will take about 3 lemons to equal the voltage of a D-Battery because lemons can't create a big voltage or else the world would run on lemons but, D-Battery's don't have a lot of voltage either.


The materials are:lemons,D-Battery,volt meter,copper wire and a zinc nail.


Independent variable: The number of lemons

Dependent Variable: The voltage

Controlled Variables: Type of battery and Volt meter


1.First i did was get 5 lemons

2.Next get a volt meter

3. Then get copper wire

4. Next get some zinc galvanized nails

5. Then roll the lemons to pop the juice pockets

6. Next put the zinc nail on one side of the lemon

7. Then put the copper wire on the other side of the lemon

8. Finally put the negative alligator clip on the zinc and the positive clip on the copper

Important Research Notes

The zinc and copper are called an electrolyte. All batteries have a positive and negative terminal. Electric current is a flow of atomic particles called electrons. Certain material called conductors allow more electrons to flow through them. Most metals, like copper, are good conductors of electricity. Electrons will flow from the negative electrode to the positive electrode. Volts measure the force moving the electrons.


Lemon battery in volts:






D- Battery in volts

1st:1.6 volts




It turns out my hypothesis was wrong because it took about two lemons to equal the voltage of a battery. My hypothesis however said it would take 3 lemons to equal the voltage.

If i could redo the investigation i would probably also try to find the amount of lemons to power a phone, car or something else people use a lot. My project taught me about amps,milliamps, volts, and how batteries work. My projects importance is probably to use everyday objects for something even more useful.

Just remember if life gives you lemons, you make a battery!
