Background of the Study
Electricity is the physical phenomena arising from the behaviour of electrons and protons caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge.
Electricity from a lemon is possible to get electricity from a lemon using strips of metal. The most readily available combination is copper and zinc. The zinc piece can be taken from the casing of an old carbon "D" cell (battery); some zinc coated nails may work as well. The copper can be a coin containing a high amount of copper. They are stuck into the lemon, and wires are attached to each one. The wires should be attached securely to form a good electrical contact. If the other ends of the wires are attached to a small bulb (flashlight bulb) there should be sufficient current to light it. Note that the metal pieces should be clean, and that they should not touch inside the lemon.
The electric current comes from the chemical reaction between the acid in the lemon and the zinc. Positively charged hydrogen in the acid oxidizes the zinc, causing electrons to flow from the zinc to the acid. In the process, some of the hydrogen in the acid is reduced to hydrogen gas. The copper merely completes the circuits.
* To observe what is happening when the two wires join together. * To be able to construct a Lemon battery.
Statement of the problem
* How can the lemon electricity help us in our daily lives?
a. Alternative Hypothesis
* It can succour the community to supply more electricity. b. Null Hypothesis
* It can't succour the community to supply more electricity.
Importance of the study
Electricity has been part of our lives. It has brought many things that surely have made many wonders and life would seem so hard without it. Electricity powers our light, heating, electronic appliances such as computers and...
