 * FINDING THE VOLTAGE OF DIFFERENT TYPES OF POTATO BATTERIES**


 * ABSTRACT**

=
The purpose of the experiment was to find which form of potato, being used as a battery produces the most energy and lights an LED the best. It was hypothesized that the generic Idaho potato would produce the most energy and light an LED the best as it was the kind of potato most often used as a battery. A section of copper wire was stuck into the potato, then a zinc nail next to it. The metals were then attached to an LED via alligator-clip wires. To measure the voltage, the battery was hooked up to a digital multimeter. The voltage was found and recorded. This was done to all of the potatoes. The blue potato produced the most voltage at .946 V. The Idaho potato battery produced .819 V. The sweet potato battery produced .88 V. The baked potato battery produced .888 V. The French fry battery produced the least energy at .81 V.======

The experiment could be improved by using even more types of potatoes, such as mashed potatoes, to see if it makes a difference. Future experiments that could be performed are using citrus fruits instead of potatoes, as such fruits as lemons, limes, and oranges have more liquid, and therefore more chemical reaction, then the potatoes. The experiment could also be done on different fruit juices to find if that could also work.
