POTATO INTO BATTERY
To lessen the consume of electric charge
We insert copper and zinc electrodes in to the potato, close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result
It did go well and the potato did give voltage to the equipment (clock) However, the energy needed depends on the potato also the voltage is not permanent for the potatoe’s voltage also runs out in a time period. d. Conclusions
therefore potato is an effective source of voltage and it can lessen the consume of electric charge however it also depends in the potato.
The researchers would like to acknowledge with sincerest gratitude the following persons for the support they gave to them in the accomplishment of this investigatory project. Our classmates, who helped us whenever we are misguided and whenever we have difficulties. Mrs, who serves as our second mother, who keeps on supporting us and serving as our guardian in school especially at times that we are in the wrong track. Parents, whom we lean on at most times. Who gave us all of the supports they can give for us to be able to study in a better school. Who keeps on providing us everything we need. And most especially to our Father God from above, who gave us the knowledge and the ability to do our project and who gave us instinct to think and decide and to know what’s right or wrong.

Background of the study
Problem general objectives
Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem:
Can Potato be used to generate electricity?
Potato juice contains many water soluble chemicals that may cause a chemical reaction with one or both of our electrodes. So we may get some electricity from that.
For this experiment we use:
A fresh potato
A Digital or Analog Multimeter to measure Voltage or Current of produced electricity. Alligator clips/ Leads
We insert copper and zinc electrodes in to the potato, close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. (Make sure to test your multimeter by connecting its Positive and Negative wires to each other that should show no current and no voltage).
Record And Analyze Data:
A digital multimeter showed 1.2 volts between the electrodes, but the analog multimeter showed a much smaller value. In other words even though the voltage between electrodes is 1.2 Volts, the speed of production of electricity is not high enough for an analog multimeter to show the exact voltage. (Analog multimeter gets its power from our potato to show the voltage, but digital Multimeter gets its power from an internal battery and does not consume any of the electricity produced by our potato, that is why it shows a larger and more accurate value). We repeated this experiment with some other fruits and all resulted almost the same. In all cases the produced voltage is between 1 and 1.5 volts, and in all cases they do not produce enough current to...
