... This theory can be easily demonstrated by hooking a coil of wire to a voltmeter and passing a magnet through it. It can be observed that the faster the magnet moves, the higher the voltage. Essentially, the same theory applies when making a generator. Reading the equation the other way suggests that ...

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.
