Ballast - Wikipedia

An electrical ballast is a device that limits the current through an electrical load. These are most often used when a load (such as an arc discharge) has its terminal voltage decline when current through the load increases. If such a device were connected to a constant-voltage power supply, it would draw an … See more An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current … See more An inductor, usually a choke, is very common in line-frequency ballasts to provide the proper starting and operating electrical condition … See more Preheating This technique uses a combination filament–cathode at each end of the lamp in conjunction with a … See more Early tube-based color TV sets used a ballast triode, such as the PD500, as a parallel shunt stabilizer for the cathode ray tube (CRT) acceleration voltage, to keep the CRT's deflection factor constant. See more Fixed resistors For simple, low-powered loads such as a neon lamp, a fixed resistor is commonly used. Because the resistance of the ballast resistor is large it determines the current in the circuit, even in the face of negative resistance introduced … See more An electronic ballast uses solid state electronic circuitry to provide the proper starting and operating electrical conditions to power discharge … See more For a lighting ballast, the ANSI ballast factor is used in North America to compare the light output (in lumens) of a lamp operated on a ballast … See more WebElectronic components have a wide range of failure modes.These can be classified in various ways, such as by time or cause.
