History of Electricity
600 B.C.E
Found out that by rubbing a hard fossilized resin (Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years.
1600
ELECTRICUS- “To produce from amber by friction”
1747
Electric charge was made up of two types of electric forces which are the attractive force and repulsive force.
1752
Kite Experiment- Proved that electricity and lightning are the same thing.
1786
SIMPLE ELECTRON CELL- FROG EXPERIMENT
1820
Danish physicist, discovered that a magnetic field surrounds a current-carrying wire, by observing that electrical currents affected the needle on a compass.
1822
a French mathematician, observed that a coil of wires acts like a magnet when electrical current is passed through it. Shortly thereafter, D. F. Arago invented the electromagnet and Joseph Henry, an American, demonstrated an electromagnetic device that was capable of lifting over a thousand pounds.
1831
Michael Faraday, an Englishman, developed a crude electric motor, but a practical motor was not developed until 1870. Both Faraday and Joseph Henry, working independently, invented the electric generator with which to power the motor.
1831
sending coded messages over wires using the electromagnetic telegraph and a code of electrical impulses identified as dots and dashes that eventually became known as “Morse Code.”
1800’s
The first person to measure the amount of electricity and magnetism generated in a circuit.
a German college teacher, formulated a law showing the relationship between volts, amps, and resistance.
Henry and Ohm demonstrated that in a long electric line it was better to have relatively high voltage and low current.
1879
A practical incandescent lamp was developed independently by Thomas Edison in America and Joseph Swan in England. Edison was the first to patent the commercially feasible incandescent lamp so he is recognized as the inventor.
1882
use of artificial lighting by powering incandescent streetlights and lamps in London and New York City.
1883
the inventor of 3-phase power distribution, the alternating current motor, wireless transmission.
the inventor of 3-phase power distribution, the alternating current motor, wireless transmission.
the inventor of 3-phase power distribution, the alternating current motor, wireless transmission.
1885
George Westinghouse, head of the Westinghouse Electric Company, bought the patent rights to Tesla’s alternating current system
1886
In America, the first alternating current power station was placed in operation, but as no alternating current motor was available, the output of this station was limited to lighting.
1883
The alternating current motor was introduced and ultimately became the most commonly used electric motor in buildings (e.g., for fans, air conditioners, and refrigerators).
1895
Large-scale electric power distribution began on August 26, 1895, when water flowing over Niagara Falls was diverted through a pa

11. HISTORY OF ELECTRICITY 1895 Large-scale electric power distribution began on August 26, 1895, when water flowing over Niagara Falls was diverted through a pair of high-speed turbines that were coupled to two 5000-horsepower generators that powered nearby manufacturing plants. Most of the occupants of large cities in the United States had electricity, yet only 10% of the Americans who lived in rural areas had electricity. 1930 1935 The Rural Electric Administration (REA) was created to bring electricity to these rural areas. The REA helped to establish hundreds of electric cooperatives that served millions of rural households.
