... tremendous influence of LEDs. I really had to dig through my junk to locate two incandescent indictors. Fuse protection (no fuse required) I opted to make it short-circuit proof by adding a resistor in series with the positive rail of U1. As a result, even if the IC shorts (as they sometimes do), R8 ...

... current delivered at the customer's site to be out of phase with the voltage. This phase difference can take two basics forms. 1) The current can “lag” the voltage when an inductive load (i.e., motors, magnetic HID ballasts) is used or 2) the current can “lead” the voltage when a capacitive load (i. ...

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.
