An inductor, usually a choke, is very common in line-frequency ballasts to provide the proper starting and operating electrical condition to power a fluorescent lamp or HID lamp. (Because of the use of the inductor, such ballasts are usually called magnetic ballasts.) The inductor has two benefits: Its reactance limits the … 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 Fixed resistors For simple, low-powered loads such as a neon lamp, a fixed resistor is commonly used. Because the … See more Preheating This technique uses a combination filament–cathode at each end of the lamp in conjunction with a mechanical or automatic (bi … 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 … See more An electrical ballast is a device that limits the current through an electrical load.
