An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit.It may be a fixed or variable resistor. A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube, which would otherwise rise to a destructive level due to the
A fluorescent fixture requires a ballast to send the proper amount of electricity to the fluorescent bulbs. The ballast provides enough voltage to start the fluorescent bulbs, and once they are started, it quickly lowers the current to produce just enough electricity to produce a steady light source
