The first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.\n\nMuch later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.\n\nIn 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.\n\nThe inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.\n\nLewis Howard Latimer (1848-1928) improved the bulb by inventing a carbon filament (patented in 1881); Latimer was a member of Edison's research team, which was called "Edison's Pioneers." In 1882, Latimer developed and patented a method of manufacturing his carbon filaments.\n\nIn 1903, Willis R. Whitney invented a treatment for the filament so that it wouldn't darken the inside of the bulb as it glowed. In 1910, William David Coolidge (1873-1975) invented a tungsten filament which lasted even longer than the older filaments. The incandescent bulb revolutionized the world.

This is my best guess based on a familiarity with the issue, but please don't take this as definitive.  I just wanted to give some answer as noone had as of yet.  \n\nAs I understand it, Edison used a voltage of 110 in his original DC systems after finding experimentally that it was the highest voltage that would illuminate his carbon filament bulbs enough to beat gaslight without burning them out too quickly.  Exactly what was considered "too quickly" I don't know.  \n\nThe first AC systems adopted the 110 V standard, although Nicolai Tesla, who developed such systems for George Westinghouse, wanted to use a higher voltage, 240 V.  \n\nLater, when some electrical systems switched to a higher voltage, they went with a multiple of 110 so as to make it easier to tap into one phase of the voltage to get the old 110 V potential back.  This is essentially what we have in the US.  We have 220 V service to our homes, and a few of the appliances that consume a lot of power, such as clothes dryers and AC systems, are wired to that, but the rest of the outlets are wired for 110.

When you ask the question "Who invented electric power?", I presume you mean the electric power distribution that we know of today.\n\nOne of the primary contributors would be Nikola Tesla, a Serbian-American electrical engineer and scientist.  He along with the Westinghouse corporation developed the three-phase AC power distribution used around the world today.  Tesla and Westinghouse corp were also heavily involved in developing new generators and motors using three-phase power.  Edison was trying to promote a relatively inefficient DC distribution system at the same time, but failed to gain widespread support.  Though Edison did create inventions, such as the light bulb, that helped make use of the ever-growing power grid.\n\nI had not heard of Gennai Hiraga before, but sounds like a pretty interesting inventor as well.

isaac newton i mean sometimes he would sit on the end of his bed half dressed thinking about gravity\n\nor maybe edison he would find like 500 ways of not making a light bulb but all he would say is "i have not failed i have found 500 more ways to not make a light bulb work!"

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.

Nikola Tesla.\n\nBecause he thought it wouldn't cause lights to flicker for anyone.

false, but the rumor probably started I believe one of Edison's bulbs is still burning in Menlo park (his lab).\n\nIt's never been turned off, which helps it last longer.

Augustine Fresnel invented the Fresnel lens. (used in lighthouse)\n\nspotlight or searchlight, In 1892 such apparatus was used along the English Channel ( I was thinking it goes back to the ancient Greeks)\n...\nIn 1916 Edison invented a portable electric apparatus powered by storage batteries. ... The electric arc was generally employed after the American inventor E. A. Sperry introduced (1915) his high-intensity arc lamp based on principles that still predominate in modern searchlight equipment.

Thomas Edison is credited with creating the incandescent light bulb. He, however, did not create it from scratch. He improved on the designs of others. He also created the generating system to power the bulbs.

I think you're confusing Thomas Jefferson with Benjamin Franklin.\n\nAnd he didn't "make" electricity, per sey, but there were significant events which prompted his interests in researching and attempting to reproduce electricity in a controlled fashion.\n\nThe main two are lightning bolts and static shock.  While technically, these are two aspects of friction and only differ in magnitude, he considered them separate entities as one was generated by air (gaseous material) and the other by tangible objects (solid material).  The third influence in his research and discovery stems back to when he was stung by a jellyfish in his youth and pondered how so simple a creature could harness such a perplexing force.

Most notably these include Luigi Galvani (1737–1798), Alessandro Volta (1745-1827), Michael Faraday (1791–1867), André-Marie Ampère (1775–1836), and Georg Simon Ohm (1789-1854).
