The ballast comes out of alternating current or direct current
It is. When lamp normal luminescence, smaller resistance, always keep open state, the starter of the electric current is stable through work lamp, ballast, lamp to normal light. Due to the ballast in fluorescent lamp work, there is always an electric current passes through, so prone to vibration, and fever, so have a ballast of fluorescent lamp, especially the ballast quality is bad, will produce very big voice, use a long time, also easy to burn out. Ballast electronic ballast and inductance ballast
Is fluorescent lamp ballast, ballast resistor) on the current limiting effect and the production of instantaneous high pressure equipment, it is enameled wire on the core of silicon steel production, the iron core coil, open/close the electricity in an instant, can produce high voltage, self inductance on the electrodes at the ends of the tube (filament)

Ac, dc is useless for ballast, because there is no electromagnetic induction.
