... Switches and Variable Resistors A switch is a device that allows the flow of electrons or stops the flow. When the switch is open, there is no flow, because there is a gap in the conductor. When the switch is closed, the switch becomes the 'gap replacement' and allows the flow of electrons to conti ...

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.
