Study The researcher‚ as one of the consumers of the electricity‚ also experiences the power crisis. Due to different factors that results to sudden brownouts especially those in the province‚ the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of

Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

There were no doubt that Myanmar people wants democracy and fought for it over decades. They participated in revolution to change the government from dictatorship to democracy. But the lack of prepared in‚ “What happens after the revolution?” They only realized that the government must needed to transfer‚ but they often was forgetting that individual and society also needed to change. People thought they would all be free to pursue their own interests and democracy after the revolution. Now it seems

his arms were very skinny‚ too skinny. Joseph was a very silent kid making him more vulnerable to bullies‚ when the people were telling him that he was fat he didn’t say anything back to them because of what he knew he was. His parents keep insisting to complain to the deputy principal‚ but what they didn’t know is that if Joseph told the teachers‚ it would make the bullies even more consistent in their acts.

there were batteries slim‚ flexible and also powerful enough to run the gadgets. The batteries‚ it turns out‚ are the main barrier to modern electronics design. But in a small‚ brightly lit lab in an office park behind the Oakland Airport in Alameda‚ Calif.‚ a young startup called Imprint Energy‚ is using research created at the University of California‚ Berkeley to develop just such a battery that could free gadget makers from the constraints of the standard lithium ion battery. Well‚ that’s

CHAPTER - 1 INTRODUCTION TO BATTERIES An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery in 1800 by Alessandro Volta‚ batteries have become a common power source for many household and industrial applications. Batteries are represented symbolically as follows Fig. 1(a) Symbolic view Fig.1(b)conventional battery Electrons flow from the negative terminal towards

ABSTRACT A Fruit battery is a device used in experiments proposed in many science textbooks around the world. It is made by inserting two different metallic objects‚ for example a galvanized nail and a copper coin‚ into an ion bridge (for example a lemon‚ a potato or paper soaked in salt water or acid). The copper coin serves as the positive electrode or cathode and the galvanized nail as the electron-producing negative electrode or anode. These two objects work as electrodes‚ causing anelectrochemical

using more and more household batteries. The average person owns about two button batteries‚ ten normal (A‚ AA‚ AAA‚ C‚ D‚ 9V‚ etc.) batteries‚ and throws out about eight household batteries per year. A battery is an electrochemical device with the ability to convert chemical energy to electrical energy to provide power to electronic devices. Batteries contain heavy metals such as mercury‚ lead‚ cadmium‚ and nickel‚ which can contaminate the environment when batteries are improperly disposed of. When
