FRUITS AS BATTERY AND SOURCE OF ELECTRICITY


The purpose of this project was to find out which fruit would generate enough electricity to light a light bulb and to discover which fruit would light the bulb the longest. To conduct my experiments I used a Multimeter, copper and zinc wires & electrodes, alligator clips with leads, various light bulbs and five types of fruits.continue..

In order to generate electricity, there must be a power source and a complete circuit. When using a citrus fruit to create electricity, these rules still apply. In a simple experiment using a citrus fruit, the components of the circuit include: a lemon or other fruit, wire, two different metal elements and a small light bulb. The lemon in this circuit serves as the battery and power source.continue..

Purpose
To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small light bulb.
Additional information
Batteries are devices that store chemical energy and convert it to electrical energy. Consisting of one or more voltaic cells, batteries come in various sizes and forms and are integrated into most electronic and portable devices. continue..

Set the fruit on a table and gently roll it around to soften it up. You want the juice to be flowing inside the fruit without breaking its skin. Alternatively, you can squeeze the fruit with your hands.
Insert the zinc and copper nails into the fruit so that they are about 2" or 5 cm apart. You don't want them to be touching each other. Avoid puncturing through the end of the fruit.continue..

Summary
Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.continue..

Vegetable Electricity Conductors
Potatoes, onions and tomatoes are all good vegetable conductors. Tomatoes are most likely the best vegetable conductor since they have the highest acidity level.
Fruit Electricity Conductors
Some good fruit electricity conductors are apples, grapefruit, oranges, lemons and limes. The citrus fruits will be excellent conductors due, again, to the high acidity level.continue..
