The Problem-And It’s Background Potato as an alternative battery for scientific calculator is the chosen topic of the researchers. The researchers thought of many topics but the topic about the scientific calculator get their attention. They thought that scientific calculator is very useful to students especially to 4th year students. A scientific calculator is a type of electronic calculator, designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in almost all traditional applications, and are widely used in both education and professional settings.

In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market. 1 The first scientific calculator with basic functions was released in 1968. And in February 1, 1972 Pocket Calculator and the world’s first hand-held scientific calculator was released by Hewlett-Packard.

Until now many brands like Casio and Sharp were releasing new models of scientific calculator with more hi-tech program. The researchers thought that the battery of scientific calculator is hard to find. It cannot be found in an ordinary market. They thought what if the user of scientific calculator runs out of battery? What if they can’t find a battery for it? What can be an alternative battery for it? The researchers want to prove and study that potato can be an alternative battery for a scientific calculator. Potato can produce and convert energy and it can be use in a scientific calculator.

The researchers thought that potato can be used by the students and users of scientific calculator because it can be found easily in the market. A potato is a starchy edible tuber native to South America and cultivated all over the world. Potatoes have been domesticated for over 10,000 years, and over one thousand varieties are known, although only a fraction of this number are cultivated commercially. Potatoes play an important role in the culture and history of many South American countries, and were adopted into European cuisine and culture when they were introduced in the 1600s. Potato is important to our daily life because it has carbohydrates that can make a person’s appetite heavy and that is why many unwealthy people are eating this and because of that it became the third most important root crop in the world. Potatoes have long been one of the most useful vegetables and one of the world’s cheapest sources of food. We love potatoes in all of their forms: chips, fries, mashed, roasted, baked, made into batteries. Wait a minute, batteries? Surprisingly, some scientists believe the ever popular spud could provide us with a terrific eco-friendly battery.

These researchers believe that treated potatoes could be the basis for a solid organic electric battery that will provide a cheap answer to the power needs of many people on our planet. 3 Carbohydrates give us energy to do things and potato has carbohydrates so it gives energy. Potato like other foods give energy to people but it will not make you feel energetic or active because of some chemical make-up in it. A battery is used to convert directly to electrical energy. It contains anions, the negatively charged ions and cation, the positively charged ions.

If the two create reactions it will give electrical energy. Potato produce and convert energy because there is a reaction occurs at the zinc anode and the copper cathode. The potato is acidic enough inside to cause a redox reaction, whereby zinc metal is oxidized from metalic zinc to zinc cations (Zn2+) and two electrons. These electrons flow to the cathode (the copper nail) to create an electrical flow. At the cathode, hydrogen ions (protons [H+], supplied by the acid in the potato) are reduced to hydrogen gas (H2).

The electricty flows through the wire attaching the two nails, and through the light bulb to light it up. In this study, a penny will be used as conductor of energy. Most penny are made of metal: nickel, copper, iron or steel. Some rare and expensive ones are made of nearly pure gold and silver. And all metals are a good conductor. 4 1 http://en. wikipedia. org/wiki/Scientific_calculator 2http://www. wisegeek. org/what-is-a-potato. htm 3http://www. eco20-20. com/Can-Potato-Batteries-Provide-a-Safer-Alternative. html 4http://wiki. answers. com/Q/Are_coins_good_conductors_of_electricity#ixzz220boSMM0
