... To get this we can find the open-circuit voltage and the short-circuit current. In this case, that is a fairly straightforward process, using the plot in Figure 2. However, it is very important that we take care about the polarities of the voltage and current. Let’s take our time and do this careful ...

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.
