In 1827, a German physicist and high school teacher named Georg Ohm (1789 – 1854) published the results of some experiments which are the basis of what we now call Ohm’s law. Ohm’s law states that, for a metal conductor, at a constant temperature, the current increases in prop ...

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.
