History of electric power transmission. Electric power transmission, the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk (formally called "transmission") and the delivery of electricity to individual customers ("distribution").
Electric power, like mechanical power, is the rate of doing work, measured in watts, and represented by the letter P. The term wattage is used colloquially to mean "electric power in watts". The electric power in watts produced by an electric current I consisting of a charge of Q coulombs every t seconds passing through an electric potential ...
Power electronics is the application of solid-state electronics to the control and conversion of electric power. Power electronics started with the development of the mercury arc rectifier in 1902, used to convert AC into DC. From the 1920s on, research continued on applying thyratrons and grid-controlled mercury arc valves to power transmission.
Electric power is generally supplied to businesses and homes by the electric power industry. Electricity is usually sold by the kilowatt hour (3.6 MJ) which is the product of power in kilowatts multiplied by running time in hours. Electric utilities measure power using electricity meters, which keep a running total of the electric energy ...
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 ...
Originally American Gas and Electric Company (AG&E), formed in 1906 from Electric Company of America. Became American Electric Power in 1958; merged with Central and Southwest Corporation in 2000. American Electric Power Company, Inc. ( AEP ), (railcar reporting mark: AEPX) is an American domestic electric utility company in the United States.
Power engineering. Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery ( transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.
History of discoveries timeline. Year. Event. 600 BC. Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber . 1600. English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660.
