Final Written Report I. Problem: Which battery lasts the longest out of two different brands Kingever‚ Eveready? II. Title: Battery Life III. Abstract: Nowadays people do not know if batteries are fully charge or completely cahrge‚ because people create some batteries baecause of "crisis". People generally used battery once and later throws it. But in many cases it is recharged for longer time in many power applications. Through batteries‚ we can use emergency lights‚ radios and other

INTRODUCTION Alessandro Giuseppe Antonio Volta is known as the scientist that founded the electric age. He was an Italian physicist pioneer that contributed greatly to the development of the battery. Alessandro Volta was born in Como‚ Italy in 1745. He attended a public school; in 1774 he was appointed professor of physics at the Royal School in Como. His first invention was an electrophorus; a device that produced static electricity. In 1776-77 he devoted his time to chemistry‚ studying atmospheric

A Laptop either can be plugged into a wall outlet or ran completely off a battery pack‚ which is built into the computer. The battery pack is easily rechargeable by plugging the batteries ac adaptor in to the wall outlet. A Desktop computer can be found in almost every building that has human contact. The desktop computer is in-fact‚ the inspiration for the laptop. A desktop

were asked to predict and then find the brightness and flow rate of a closed circuit with a three cell battery pack‚ a long bulb‚ a capacitor parallel to the long bulb‚ and a round bulb. I originally predicted that the round bulb would be brighter when the circuit was first closed and when the circuit reached a steady state‚ and that the wire between the round bulb and the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady state the long bulb was actually

ABSTRACT This study aims to make an improvised traveling charger that will use heat or waste heat to charge a battery. It is not new to us that we are lacking for the supply of the electricity and being in the modern times‚ we can’t live without cell phones and how does we able to charge the battery if there’s no supply of electricity. The researcher used scrap materials that can be easily found. They used copper and iron plate‚ some adhesives copper wires and the normal traveling charger to construct

OF PRODUCT DEVELOPMENT AT DELL COMPUTER CORPORATION Abstract Dell’s Portable Division‚ headed by Mark Holliday‚ had reached a decision point in the development of its new laptop computer. Holliday had to decide‚ or reach consensus on‚ what kind of battery Dell would put into its new line of laptop computers. It was the second try for Dell in the laptop market. The first attempt had failed due to technical problems‚ costing the company $20 million in development expenses alone. After the failed earlier
