Electricity is important in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past about electricity enabled such things as engines‚ telephones‚ radios‚ computers‚ and much‚ much more. As early as 600 B.C.‚ the Greeks were already studying electricity. They noticed that if you rubbed a piece of amber with fur‚ it had a charge with the ability to attract small objects. Many years later‚ in the 16th Century‚ William Gilbert discovered many

A Career in Electrical Engineering A career in electrical engineering means solving problems associated with large-scale electrical systems. Sometimes the term is used to include electronic engineering but jobs in this field involve small scale systems such as computers and integrated circuits.it might be said that a job in electronic engineering involves transmitting information and a job in electrical engineering involves transmitting energy. Alternatively electronics power transmission control

Early History of Electric Power Date Event Pictures 1800-1819 Early electric experiments were performed with DC. In 1800‚ Alessandro Volta published a description of a silver/zinc battery‚ acknowledging that he did not know how it worked. In 1807‚ Humphry Davy constructed a practical battery (the picture will be immediately familiar to anyone who works with UPS systems)‚ and demonstrated both incandescent and arc light. • Volta’s famous bi-metalic frog twitch (I did this one myself as a boy..

Electricity was not discovered by one scientist‚ but by various scientists who built on the knowledge they have of it. These were scientist such as Benjamin Franklin‚ Alessandro Volta‚ Michael Faraday‚ Thomas Edison and George Westinghouse. Benjamin Franklin discovered electricity with his famous kite-flying experiments in 1752. Alessandro Volta‚ an Italian scientist in 1800 soaked paper in salt water‚ placed zinc and copper on opposite sides of the paper‚ and watched the chemical reaction produce an electric

Electrolysis Feb. 22‚ 2012 Introduction: Jan Rudolph Deiman and Adriaan Paets van Troostwijk used in 1789 an electrostatic machine to produce electricity which was discharged on electrodes in a jar with water. In 1800 Alessandro Volta invented the voltaic pile‚ a few weeks later William Nicholson and Anthony Carlisle used it for the electrolysis of water. When Zénobe Gramme invented the Gramme machine in 1869 electrolysis of water became a cheap method to produce hydrogen. A method of industrial

But unlike its counterpart hearing aids‚ which makes sound louder‚ cochlear implants do the work of damaged parts of the inner ear(cochlea) to provide sound signals to the brain. It all started with Alessandro Volta when he managed to stimulate his internal ear by using an electrical current the year 1800. Since that time there have been major modifications from the look and all the way to the pitch and stimulation

Potato Batteries: Veggie power! Data and Analysis Background The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this electrical energy to light a flashlight‚ to start a car‚ or to listen to your favorite music. We made a simple battery out of a potato by placing in it a zinc strip and a copper strip. At the zinc strip‚ the
