Schenectady, New York
Schenectady () is a city in Schenectady County, New York, United States, of which it is the county seat. As of the 2020 census, the city's population of 67,047 made it the state's ninth-largest city by population. The city is in eastern New York, near the confluence of the Mohawk and Hudson rivers. It is in the same metropolitan area as the state capital, Albany, which is about southeast. Schenectady was founded on the south side of the Mohawk River by Dutch colonists in the 17th century, many of whom came from the Albany area. The name "Schenectady" is derived from the Mohawk word ''skahnéhtati'', meaning "beyond the pines" and used for the area around Albany, New York. Residents of the new village developed farms on strip plots along the river. Connected to the west by the Mohawk River and Erie Canal, Schenectady developed rapidly in the 19th century as part of the Mohawk Valley trade, manufacturing, and transportation corridor. By 1824, more people worked in manufac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Federal Telegraph Company
The Federal Telegraph Company was a United States manufacturing and communications company that played a pivotal role in the 20th century in the development of radio communications. Founded in Palo Alto, California in 1909 by Cyril Frank Elwell, the company would eventually merge in August 1927 with the Mackay Companies. In 1911-13, Lee De Forest and two assistants worked at FTC on the first vacuum tube amplifier and oscillator, which De Forest called the "Oscillaton" after his earlier Audion. The company remained a separate entity within the Mackay Companies, however, and when International Telephone and Telegraph (ITT) purchased the Mackay Companies in 1928 Federal remained a component of the Mackay structure as a manufacturing entity. In 1931, Dr. Ernest O. Lawrence, inventor of the cyclotron, convinced Federal Telegraph to donate an 80-ton magnet they had developed for a canceled project in China to his first cyclotron project on the campus of the University of Californi ...

Arc Converter
The arc converter, sometimes called the arc transmitter, or Poulsen arc after Danish engineer Valdemar Poulsen who invented it in 1903, was a variety of spark transmitter used in early wireless telegraphy. The arc converter used an electric arc to convert direct current electricity into radio frequency alternating current. It was used as a radio transmitter from 1903 until the 1920s when it was replaced by vacuum tube transmitters. One of the first transmitters that could generate continuous sinusoidal waves, it was one of the first technologies used to transmit sound (amplitude modulation) by radio. It is on the list of IEEE Milestones as a historic achievement in electrical engineering. History Elihu Thomson discovered that a carbon arc shunted with a series tuned circuit would "sing". This "singing arc" was probably limited to audio frequencies. Bureau of Standards credits William Duddell with the shunt resonant circuit around 1900. The English engineer William Duddell discov ...
