Fruit Battery Experiment

The two metal that have been recommended for this experiment is copper and zinc or galvanized. My experiment could have been improved by testing the fruits more than once by using more than of each fruit to get a wider range of data. Short circuits are bad because they can cause batteries to drain very quickly and overheat luckily, potato batteries can only supply a small amount of current, so short circuits in this experiment are not dangerous. Zinc and Copper make great battery terminals. So, what are you waiting for? With the nails inserted into the citrus fruit, it is time to prepare your bulb. Boiled and chopped stem is also suitable, according to Sri Lankan researchers. Use a ruler to make sure you space the electrodes the same distance apart and insert them to the same depth in each potato for example, 2 cm apart and 3 cm deep.

It has positive and negative pins, and it will not work at all if it is connected backwards. Setup for making sure the multimeter has a working fuse. It only works when you have two different materials, close together but not touching in the lemon. Now tell them you will do it with a potato! The lemon battery is a favorite of science fair participants since it is easy and fun to replicate. You should start out with your dial settings at 20 V for measuring voltage or 20 mA for measuring current. The highest voltage we recorded was created by citric acid from the orange and the zinc-coated nail. Archived from on April 15, 2009.

How to Make a Lemon Battery

When the battery is hooked up to an external circuit and a significant electric current is flowing, the zinc electrode loses mass, as predicted by the zinc oxidation reaction above. For example, you might have your electrodes or alligator clips connected incorrectly to your vegetables. Make sure your potatoes are fresh. How long does it take for the battery to drain? That means only a few ions will move from one coin to the other and you will have low voltage readings. If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. Only free charge will flow from one cell to another through the metal-to-metal contact.

Fruit/Veg Batteries

Touch your tongue to the copper wire. The nails act as poles for the battery, one positive and one negative. Note The size of the light bulb will affect how brightly it's lit. You need to remove enough insulation so you can wrap the exposed wire around the nails. Just make a second battery and connect the zinc or steel piece of one battery with the copper wire of the other battery using another piece of copper wire to act as a bridge. In a potato battery, the electrical energy is generated by two chemical reactions that happen at the electrodes the copper and zinc metal strips.

Fruit/Battery Experiment

Zinc atoms enter the electrolyte as ions missing two electrons Zn 2+. It will require a 9 V battery, which is not included in your Veggie Power kit. Make sure not to squeeze too tightly and break the skin! That is the conservation of energy; no energy is created of destroyed only transformed. About the same Do you agree? I'm sure there are other questions, but these should get you started. If the terminals in our experiment are not connected to the meter, no voltage potential can be read. I believe this fruit to be a lemon as they are extremely sour.

I look forward to hearing how you did in the competition. The ends sharp tips of the nails should be in the center of the fruit, but not touching one another. For further information, consult your state's handbook of Science Safety. If we do use the right metals for our terminals, and we connect the voltmeter, we will get a voltage reading. Batteries power many things around you, including cell phones, wireless video game controllers, and smoke detectors.

Ask an Expert: Fruit/Vegetable BATTERY

Experiment 1: Voltage and Amperage Obtained From Various Electrolytic Substances Introduction: This experiment is conducted to determine the voltage and amperage created by electrolytic reactions in various electrolytes are different, and if so how much. A battery created from a simple, everyday lemon illustrates quite well how electricity works. For the students — as long as we have the right metals in the lemon, and we connect the voltmeter to each of those metals battery terminals , we will read a voltage on the meter. The next step is to puncture the citrus fruit with the nails. As described somewhat later by Goodisman, this effect is unrelated to the evolution of hydrogen that occurs when the cell is providing electric current to an external circuit; the hydrogen associated with these currents evolves from the copper electrode. Thanks for your help, Rpedneka Rpedneka - A veggie or fruit based battery will generate an electro-potential voltage and current when electrodes of differing material are used.

Fruit/Veg Batteries

The results of the experiment were that one fruit was not able to power a light bulb. Yes, you can actually use fruits and vegetables as part of an electric power source! Has your flashlight ever stopped working because the batteries were dead? Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. If you are looking to test a variable, try making batteries using different fruits and vegetables. The first real improvement over the plain zinc-copper in acid cell was due to Dr. Batteries connected in series and parallel. You can think of this as positive voltage going one way, but being immediately cancelled out by negative voltage going the other way. The lemon battery gave off a lot less voltage than the store bought batteries, but still had the average of.
