13.10 * How series and Parallel Circuits Differ
... If you connected 3 bulbs in series they would not be as bright as if there were only 1 or 2bulbs in the circuit This is because the battery can only provide so much potential difference to each electron that leaves the source. The energy is then distributed across all loads in the circuit See ...

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.
