... 19) Why does an electric component (resistor) become hot when current passes through it ? (2) Ans: • There is energy transfer so resistor heats up. • Energy transfer is because • electrons collide with ions in the lattice as they move through it. • These collisions give ions extra energy which is e ...

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.
