... You can often connect LEDs to give a visual indication of a 1 (LED lighted) or a 0 (LED dark). Here some LEDs are shown, together with a 470 current limiting resistor. If you connect LED indicators to your circuit remember that an LED is not the same in both directions, and you have to get the corr ...

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.
