Can a lemon produce electricity science fair project.

It is possible to produce electric current using the acidic properties of lemon. From our very first circuit bugs creation to potato batteries we have had a lot of fun over the years experimenting with low voltage experiments and electricity in our elementary science lessons with summer here that means lemons and lemonade. However a series of lemons can be used to increase the voltage of the whole battery. Building an electro chemical battery with a lemon is the classic science fair experiment.

Your battery can generate electricity but will only do so when the electrodes are connected with something that conducts electricity. The voltage produced by a single lemon is very small. To create a connection attach the second aluminum strip to the part of the penny sticking out of the lemon with a plastic coated paperclip. Although you can use almost any fruit or potato all you need is one galvanized nail and a single copper penny although using a copper nail works better.

I learned that oranges produce the least amount of ohms. The zinc and the copper must be as far away from each other as possible on not touch inside the lemon. Make sure the aluminum touches the penny so electricity can pass between the copper penny and the aluminum foil. However doesn t produce any electrons on its own.

You can test another person to see if he or she can feel the electricity or you can opt to add one more lemon battery to your set extra. When you attach two electrodes to a lemon and touch your tongue to both of them at the same time it completes an electrical circuit making an electric current pass through the tongue giving it a tingling sensation or a metallic taste. A series involving four lemon batteries can easily light an led. It also means it was time for us to create the famous lemon battery science experiment.

Now that you can detect whether electricity is generated. In a battery the chemical energy is converted into electrical energy. Insert a zinc coated nail also known as galvanized into the lemon through one side and insert a copper penny into the other. 4 lemons produce 2 volts of electricity we will need 16 lemons to power a 8 volt light bulb.

Limes only create 30 ohms making the lemon have the most citric acid for producing electricity. We love building circuits around here. Thus lemon just serves as an environment for the generation of electricity.
