Voltages used for electric power transmission increased throughout the 20th century. [50] The first "high voltage" AC power station, rated 4-MW 10-kV 85-Hz, was put into service in 1889 by Sebastian Ziani de Ferranti at Deptford, London. [33] The first electric power transmission line in North America operated at 4000 V.
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. [1] [2] [3] He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. [4]
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720: English scientist Stephen Gray made the distinction between insulators and conductors. 1745
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s: arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
This association gave rise to the English words "electric" and "electricity", which made their first appearance in print in Thomas Browne's Pseudodoxia Epidemica of 1646. [11] Isaac Newton made early investigations into electricity, [12] with an idea of his written down in his book Opticks arguably the beginning of the field theory of the ...
An iron is a small appliance used to remove wrinkles from fabric. The electric iron was invented in 1881 and patented in 1882 by Henry W. Seely of New York. A second electric iron, a "cordless" one instead heated on a stand powered by electricity, was developed with his partner Dyer in 1883. [238] 1881 peristaltic pump
An electric current passing through the wire creates a Magnetic field, with a north pole at one end and a south pole at the other. The first application of electricity that was put to practical use was electromagnetism. [18] William Sturgeon invented the electromagnet in 1825. [19]
