... Here we will use voltage dividers to find the voltages across the 1, 2, and 3 kΩ resistors. For n series-connected resistors, if we know the total voltage across all of the resistors, the voltage across one resistor is the total voltage * the ratio of its resistance to the total resistance. See the ...

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.
