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.

Born in Columbus, Ohio, in April 23, 1856, Granville T. Woods dedicated his life to developing a variety of inventions relating to the railroad industry. To some he was known as the "Black Edison, both great inventors of their time. Granville T. Woods invented more than a dozen devices to improve electric railway cars and many more for controlling the flow of electricity. His most noted invention was a system for letting the engineer of a train know how close his train was to others. This device helped cut down accidents and collisions between trains. \n\nGranville T. Woods literally learned his skills on the job. Attending school in Columbus until age 10, he served an apprenticeship in a machine shop and learned the trades of machinist and blacksmith. During his youth he also went to night school and took private lessons. Although he had to leave formal school at age ten, Granville T. Woods realized that learning and education were essential to developing critical skills that would allow him to express his creativity with machinery. \n\nIn 1872, Granville T. Woods obtained a job as a fireman on the Danville and Southern railroad in Missouri, eventually becoming an engineer. He invested his spare time in studying electronics. In 1874, Granville Woods moved to Springfield, Illinois, and worked in a rolling mill. In 1878, he took a job aboard the Ironsides, a British steamer, and, within two years, became Chief Engineer of the steamer. Finally, his travels and experiences led him to settle in Cincinnati, Ohio, where he became the person most responsible for modernizing the railroad. \n\nIn 1888, Granville T. Woods developed a system for overhead electric conducting lines for railroads, which aided in the development of the overhead railroad system found in cities such as Chicago, St. Louis, and New York City. In his early thirties, he became interested in thermal power and steam-driven engines. And, in 1889, he filed his first patent for an improved steam-boiler furnace. In 1892, a complete Electric Railway System was operated at Coney Island, NY. In 1887, he patented the Synchronous Multiplex Railway Telegraph, which allowed communications between train stations from moving trains. Granville T. Woods' invention made it possible for trains to communicate with the station and with other trains so they knew exactly where they were at all times. \n\nAlexander Graham Bell’s company purchased the rights to Granville T. Woods’ "telegraphony," enabling him to become a full-time inventor. Among his other top inventions were a steam boiler furnace and an automatic air brake used to slow or stop trains. Wood’s electric car was powered by overhead wires. It was the third rail system to keep cars running on the right track. \n\nSuccess led to law suits filed by Thomas Edison who sued Granville Woods claiming that he was the first inventor of the multiplex telegraph. Granville Woods eventually won, but Edison didn’t give up easily when he wanted something. Trying to win Granville Woods over, and his inventions, Edison offered Granville Woods a prominent position in the engineering department of Edison Electric Light Company in New York. Granville T. Woods, preferring his independence, declined.

He was a Serbian-American inventor, physicist, mechanical engineer and electrical engineer. Tesla is recognized among the most accomplished scientists of the late 19th and early 20th century. His patents and theoretical work form the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution system and AC motor, with which he helped usher in the Second Industrial Revolution.

Thomas Jefferson (April 13, 1743 N.S. – July 4, 1826) was the third President of the United States (1801–1809), author of the Declaration of Independence (1776), and one of the most influential founders of the United States. Major events during his presidency include the Louisiana Purchase (1803), the Embargo Act of 1807, and the Lewis and Clark Expedition (1804–1806).\n\nAnd check out the link below.

Lots of jobs are far more important than politics. Who grows you food? Who built you houses? Who provides electricity and water?

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.

There's debate that that actually happened.  The prevailing theory of the time was though, no joke, that in order to study electricty, you first had to experience it first hand.\n\nOther things he did:\nhttp://en.wikipedia.org/wiki/Benjamin_Franklin

Sounds pretty straightforward to me. Have you made up the list of principles that Jefferson advocated in his pre-presidential days? If not, that would be a good starting point. \nYou can probably find this information by putting Thomas Jefferson into your search engine. \nGood luck!

Ben Franklin was one of the founding fathers of the of the United States.\nBen Franklin discovered electricity wa sproduced by lightening with his key on a kite experiment.\nBe Franklin in his youngr years secretly wrote Poor Richards Altmac whic became a best seller of his time.\nFrankin Was very instrumental in getting aid for the American Colonists from France an dothers during the Revolutionary war.\n\nThe   http://en.wikipedia.org/wiki/Ben_Franklin   gives this description of  Franklin.                       \nBenjamin Franklin (January 17, 1706 [O.S. January 6] – April 17, 1790) was one of the best known Founding Fathers of the United States. He was a leading author, politician, printer, scientist, philosopher, publisher, inventor, civic activist, and diplomat. As a scientist he was a major figure in the history of physics for his discoveries and theories regarding electricity. As a political writer and activist he, more than anyone, invented the idea of an American nation[1], and as a diplomat during the American Revolution, he secured the French alliance that made independence possible.\n\nFranklin was noted for his curiosity, his writings (popular, political and scientific), and his diversity of interests. His wise and scintillating writings are proverbial to this day. As a leader of the Enlightenment, he gained the recognition of scientists and intellectuals across Europe. An agent in London before the Revolution, and Minister to France during it, he more than anyone defined the new nation in the minds of Europe. His success in securing French military and financial aid was the turning point for American victory over Britain. He invented the lightning rod; he was an early proponent of colonial unity; historians hail him as the "First American". The city of Philadelphia, Pennsylvania marked Franklin's 300th birthday in January 2006 with a wide array of exhibitions, and events citing Franklin's extraordinary accomplishments throughout his illustrious career.\n\nBorn in Boston, Massachusetts to a devout Anglican tallow-maker, he was baptized at Old South Meeting House. Franklin learned printing from his older brother and became a newspaper editor, printer, and merchant in Philadelphia, becoming very wealthy. He spent many years in England and published the famous Poor Richard's Almanac and the Pennsylvania Gazette. He formed both the first public lending library and fire department in America as well as the Junto, a political discussion club.\n\nHe became a national hero in America when he spearheaded the effort to have Parliament repeal the unpopular Stamp Act. A diplomatic genius, Franklin was almost universally admired among the French as American minister to Paris, and was a major figure in the development of positive Franco-American relations. From 1775 to 1776, Franklin was Postmaster General under the Continental Congress and from 1785 to his death in 1790 was President of the Supreme Executive Council of Pennsylvania. Towards the end of his life, he became one of the most prominent abolitionists.\n\nFranklin was interested in science and technology, carrying out his famous electricity experiments and inventing, in addition to his very important lightning rod, the Franklin stove, catheter, swimfins, glass harmonica, and bifocals. He also played a major role in establishing the University of Pennsylvania and Franklin and Marshall College. He was elected the first president of the American Philosophical Society Held at Philadelphia for Promoting Useful Knowledge, the oldest learned society in the United States, in 1769. In addition, Franklin was a noted linguist, fluent in five languages. He is typically recognized as a polymath.
