... For example, if I have a fuse that’s rated at a voltage of 32 volts DC, will it protect my car that’s running a 72 volt battery pack? The answer here is very much NO. The system at 72 volts would have enough potential to arc across the gap in the blown fuse, making the fuse worthless. Put another wa ...

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.
