THE 555 INTEGRATED CIRCUIT (IC) TIMER
... devices operate in order to make simple use of the 555 timer! It turns out that we can think of the 555 as a SPDT switch that provides an output which is either a DC voltage (VCC) or 0 volts (GROUND). The position of the switch is determined by the voltage at pin #6 (THRESHOLD). This is illustrated ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. 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 destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
