Ben Franklin discovered electricity when he was visiting Mars. They have electrical storms something fierce up there, if memory serves me correctly.

My hero is Thomas Alwa Edison.Because he has done many things for a better world.Electric blub, Gramophone,film projector and sound recording device are some of his great inventions done for the mankind.

the latest issue of popular mechanics has an article devoted just to this topic.  John Koza is the inventor.\n\nif i recall, the machine reinvented several patents from scratch, invented a complex lens system, as well as differnet kinds of circuits.  \n\nNASA has recently bought a revolutionary antennae that the computer created.\n\ninventions that were reinvented were:\n\n"Jones swiftly rotates through several other recent inventions, all generated using the same technique as the lens system. There are logic circuits and amplifiers and filters, some of them suitable for the challenging low-power requirements of cellphones and laptops. Each took between one day and one month to evolve, generating an electricity bill of more than $3,000 a month."

you probably need history of electricity. lte me give you a brief one.\nFrom the writings of Thales of Miletus it appears that Westerners knew as long ago as 600 B.C. that amber becomes charged by rubbing. There was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances and coined the term electricity from the Greek word for amber. As a result, Gilbert is called the father of modern electricity. In 1660 Otto von Guericke invented a crude machine for producing static electricity. It was a ball of sulfur, rotated by a crank with one hand and rubbed with the other. Successors, such as Francis Hauksbee, made improvements that provided experimenters with a ready source of static electricity. Today's highly developed descendant of these early machines is the Van de Graaf generator, which is sometimes used as a particle accelerator. Robert Boyle realized that attraction and repulsion were mutual and that electric force was transmitted through a vacuum (c.1675). Stephen Gray distinguished between conductors and nonconductors (1729). C. F. Du Fay recognized two kinds of electricity, which Benjamin Franklin and Ebenezer Kinnersley of Philadelphia later named positive and negative.\n\nThe Leyden Jar and the Quantitative Era\n\nProgress quickened after the Leyden jar was invented in 1745 by Pieter van Musschenbroek. The Leyden jar stored static electricity, which could be discharged all at once. In 1747 William Watson discharged a Leyden jar through a circuit, and comprehension of the current and circuit started a new field of experimentation. Henry Cavendish, by measuring the conductivity of materials (he compared the simultaneous shocks he received by discharging Leyden jars through the materials), and Charles A. Coulomb, by expressing mathematically the attraction of electrified bodies, began the quantitative study of electricity.\n\nA new interest in current began with the invention of the battery. Luigi Galvani had noticed (1786) that a discharge of static electricity made a frog's leg jerk. Consequent experimentation produced what was a simple electron cell using the fluids of the leg as an electrolyte and the muscle as a circuit and indicator. Galvani thought the leg supplied electricity, but Alessandro Volta thought otherwise, and he built the voltaic pile, an early type of battery, as proof. Continuous current from batteries smoothed the way for the discovery of G. S. Ohm's law (pub. 1827), relating current, voltage (electromotelinks" href="/encyclopedia/O/Ohmslaw.html">Ohm's law), and of J. P. Joule's law of electrical heating (pub. 1841). Ohm's law and the rules discovered later by G. R. Kirchhoff regarding the sum of the currents and the sum of the voltages in a circuit (see Kirchhoff's laws) are the basic means of making circuit calculations\nyou do need advanced studying in this but i think this will help u anywhere. best of luck!!

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

Leonardo da Vinci.  Not a scientist, per se, but he did explore scientific thought and was a remarkable engineer and inventor.  Fascinating guy.

william gilbert\n\nWilliam Gilbert first coined the term "electricity" from the Greek word for amber. Gilbert wrote about the electrification of many substances in his "De magnete, magneticisique corporibus". He was also the first person to use the terms electric force, magnetic pole, and electric attraction.

Nobody invented electricity - it is a naturally occuring phenomenon (for example - lightning) that has been around as long as Earth. Benjamin Franklin is often credited with discovering the properties of electricity (although this is probably a myth), and Thomas Edison invented the electric light.

His name was Alessandro Volta.  Alessandro Volta discovered the first practical method of generating electricity.  In 1800, he arranged zinc and copper discs in a column and invented the battery.  His most famous invention was the voltic pile. \n\nThese links should give you all the good stuff!
