Orange Battery

Topics: Battery, Voltage, Resistor Pages: 11 (3847 words) Published: August 8, 2012
Like a lemon or a potato, an orange can produce electricity if a copper and zinc terminals are inserted in it. The copper terminal is positive whereas the zinc is negative. The chemical reaction inside the potato causes the electrons to move from the zinc to the copper. The experiment was demonstrated by Mustafa Daif and assited by Fatima Ali.

Veggie Power! Making Batteries from Fruits and Vegetables

Project Kit Available!

Abstract
Did you know that you can get electricity out of a potato? In this project you will learn how do build a simple battery using a variety of different fruits and vegetables - REALLY! You'll be able to figure out things like: How many lemons does it take to turn on a light bulb? Does an orange make a better battery than a potato? Can you use each segment of a grapefruit to make a super-grapefruit battery? You will also learn some of the basics of electricity and circuits: What is voltage? What is current? What is resistance? How much power can you get out of a veggie battery? Does an orange battery run out of "juice"? So, do a little produce shopping and then learn about batteries and electricity. Objective

The goal of this project is to make batteries from fruits and vegetables using metal electrodes. You will use a digital voltmeter along with resistors and other loads to determine the voltage, current, and power that your batteries can produce. Introduction

Figure 1. Pictorial (top) and schematic (bottom) diagrams of batteries connected in series. Connecting battery cells in series increases the total voltage available. The total current available remains equal to the current of a single cell. If a battery or a voltaic cell doesn't provide enough current, you can connect a number of batteries or cells together in parallel (see Figure 2 below). This keeps the total voltage the same, but now the total current that can be provided is the sum of the currents from each of the...
