Alternating Current Circuits
... As currents rise in a coil, the magnetic field around the conductor produces a counter voltage that opposes the current flow causing it to rise slowly before being released. This type of opposition to current flow causes current to lag behind voltage producing a type of resistance called inductivere ...

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.
