... What do the terms "peak inrush current" and "exciting current" mean and how do they relate to transformers? Exciting current is the amount of amperage a transformer draws under a no load condition. Another way to look at it is that exciting current is the transformer's "idling" current. Exciting cur ...

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.
