Did you know?
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.
