Lemon battery

8 August 2016

Several people had an experiment on conducting electricity with various fruits (lemon, kiwi, tomato, orange, and grapefruit). However, the researcher’s focused on generating electricity using a lemon. Somehow, in different area Lemon have many uses thus it has also many benefits. Normally, lemon is as flavor pies, pudding, frosting, candies, jams, and marmalades. They are served with fish and some kinds of meat. Lemon juice is used in salad dressings and in tea. Lemonade is popular hot-weather drink. In the other hand, Lemon is also good for health.

Fruit is convenient, because it provides both the electrolyte and a simple way to support the electrodes. The acidity, which is measured by the pH, varies substantially. Lemon, a small evergreen tree native to Asia and the tree’s ellipsoidal yellow fruit. The fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind (zest) are also used in cooking and baking. The juice of the lemon is about 5% to 6% citric acid, which gives lemons a sour taste. The distinctive sour taste of lemon juice makes it a key ingredient in drinks and foods such as lemonade.

Lemon juice in its natural form generally has a high PH that makes it hard to consume as it is without neutralizing it. To allow harmless consumption it is mixed with vitamins and additives that make it less acidic to levels of between 2. 2 and 3. 0 PH which is good for general consumption. However using it as a food is just one of the uses that lemon juice is put into. The high acidity found in lemon juice can actually be used to generate electricity. Lemons contain acid that has both positive and negative ions. These ions are usually found in the water the liquid part of the lemon.

This can be easily illustrated by carrying out a simple experiment to find out if a lemon contains these ions. For understanding how electricity is produced in a lemon we will go through the basic principle of transfer of electrons and electro-chemical reactions. The juice of lemon is acidic in nature and works as a powerful electrolyte. The lemon itself serves as a reservoir for transfer of electrons to and from the electrodes. When the two electrodes, copper and zinc, are suspended in the acidic lemon juice, the atomic structure of the atoms of both the electrodes starts breaking, resulting in production of individual electrons.

Both the electrodes are not in contact with each other and thus a flow of electrons is generated through the electrodes and electrolyte. The copper acts a positive electrode and the zinc acts as the negative electrode. Both the metals are good conductors of electricity and thus a flow of electrons take place from the negative to positive electrode. This free flow of electrons results in the generation of an electric potential. Depending on this electrons flow rate, the amount of voltage generated is measured using a voltmeter. Thus this experiment proves that electricity can also be generated just by plain chemical reaction.

However, it is to note that electricity will be generated only when the battery circuit gets completed by external wiring. Also, it is not the lemon which is the source of energy, but the chemical change in the zinc that produces electricity. The zinc electrode, when inside the lemon, gets oxidized by releasing electrons and goes to a lower energy state. This leads to the transfer of electrons from a high energy state electrode to a low energy state electrode. Thus, lemon just serves as an environment for the generation of electricity; however doesn’t produce any electrons on its own. The voltage produced by a single lemon is very small.

However, a series of lemons can be used to increase the voltage of the whole battery. A series involving four lemon batteries can easily light an LED. Although a lemon does not have enough power to light a large flashlight, it can conduct electricity and you can run an experiment to light up a small light bulb to see the proof. This experiment works with other citrus fruits as well. However, lemons work the best because lemons are one of the more acidic citrus fruits. It is important to note when exploring how lemons produce electricity, that lemons, specifically lemon juice on its own, cannot produce an electric current.

Lemon juice has to react with a metal element in order to yield a current of flowing electrons. The researchers designate this topic for they would want to lucubrate and seek answer for their questions. The researchers’ acquisition’s interesting and worth lucubrating. B. Statement of the problem 1. How long the lemon does generates? 2. Will the lemon generate electricity? 3. What are the smaller electronically gadgets and devices that the lemon could afford to generate with adequate electricity? C. Hypotheses 1.

The lemon will generate electricity for a long period of time. 2. The lemon will generate electricity. 3. The smaller electronically gadgets like wrist watch, small light bulb etc. D. Significance of the study This research is compelling because it is also for the researchers’ profit. It is not only for the researchers’ profit but also for any students or anyone who would want to use this as a substitution for their clocks or small light bulb that might lost its’ battery life. This could also be profitable which could be use in a science fair or school activities.

In a household this research could be convenient; specifically if such people would want to try and find out its good benefits towards their small electronic gadget that is out of power. In the other, although the product batteries are recommended for the people to use, it’s not however bad on using alternative fruits to make their electronically gadgets work. Thus it could even give them new knowledge and furthermore conclusive findings. Science fair is a common school activity. Students are having an exhibit on showing up new discovered things or showing up inventions; inventions that are at their strength and level.

They could use this research upon this activity. E. Scope and limitations This lemon generator could only give a small amount of electricity; which could also just be use for small electronic gadget which requires a battery. Thus, this study is focused on lemon generating small electronic gadget and not with gadgets or appliances that needed great amount of electricity like an air-conditioner, television etc. The experiment will be done in any of the researchers’ residence. The experiment upon the electronic gadget and the lemon will be timed which however will have its own data. The researchers will set two types of elec.

Gadget for the test. In the other hand, the researchers will assign five respondents -respondents for the survey that the researchers will prepare. The measured time for the experiment would be 2 days or 3. It depends upon when the lemon will lose its potential to generate our prepared small electronic gadgets. In the other hand, we will have our respondents presence while we are conducting the research thus to make them see and convince if the lemon is really beneficial. After the lemon lose its potential to generate a further electricity to power it up, we will now ask them one by one and have their answers jotted in our data.
