Ballasts vary greatly in complexity. They may be as simple as a resistor, inductor, or capacitor (or a combination of these) wired in series with the lamp; or as complex as the electronic ballasts used in compact fluorescent lamps (CFLs) and high-intensity discharge lamps (HID lamps). 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 resistance of the ballast resistor is large it determines the current in the circuit, even in the face of negative resistance introduced … See more Preheating This technique uses a combination filament–cathode at each end of the lamp in conjunction with a … See more 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 … See more 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. … 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 WebDec 15, 2024 · A fluorescent fixture requires a ballast to send the proper amount of electricity to the fluorescent bulbs.

WebThe purpose of the ballast in the circuit It turns out that for the functioning of a fluorescent lamp, it is necessary not only to ensure the flow of current, but also to apply voltage to it. Therefore, the inclusion circuit uses ballast - resistance. WebBallast is used to help light up fluorescent lamps. The ends of the fluorescent lamp have electrodes which need preheating to a substantially high temperature for the lamp to start. During this initial phase, the ballast opposes the setting up of current flowing through the electrodes into the starter to prevent damage. imperial hobby productions website
