Electrical ballast Wikipedia

An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical 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 a destructive level due to the negative differential resistance of the tube's voltagecurrent characteristic.

The complete guide to ballasts for fluorescent lights

A magnetic ballast (also called a choke) contains a coil of copper wire. The magnetic field produced by the wire traps most of the current so only the right amount gets through to the fluorescent light. That amount can fluctuate depending on the thickness and length of the copper wire.
