In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped ferrite bead strung on a wire.
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.

Generac's power systems range in output from 800 watts to 9 megawatts, [7] and are available through independent dealers, retailers and wholesalers. [6] Generac is headquartered in Waukesha, Wisconsin , [ 3 ] [ 4 ] and has manufacturing facilities in Berlin , Oshkosh , Jefferson , Eagle , and Whitewater ; all in Wisconsin.
The "Predator" is a 5.2 L; 315.1 cu in (5,163 cc) variant of the "Coyote" engine utilizing a cross-plane crank and a supercharger, which is installed in the Mustang Shelby GT500 starting in 2020 and the Ford F-150 Raptor R starting in late 2022. The engine has an output of 760 hp (570 kW; 770 PS) and 625 lb⋅ft (847 N⋅m) of torque in the ...
Special lamps were manufactured that were rated at 170 volts and 120 watts. The lamp had a thermal starter built into the 4 pin base. The power requirements were much larger than using an inductive ballast (though the consumed current was the same), but the warmer light from the lamp type of ballast was often preferred by users particularly in ...
Single-phase generator (also known as single-phase alternator) is an alternating current electrical generator that produces a single, continuously alternating voltage. Single-phase generators can be used to generate power in single-phase electric power systems.
The Pratt & Whitney PW4000 is a family of dual-spool, axial-flow, high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D.It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987.
Choke valves are important for naturally-aspirated gasoline engines because small droplets of gasoline do not evaporate well within a cold engine. By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally greater amount of fuel to be pushed from the ...
