Find the Thévenin equivalent circuit at terminals A,B - Rose

... Remember that a Thévenin equivalent looks like a series voltage source and resistance. We’ll use two methods to find Thévenin resistance. First, we’ll remember that the open circuit voltage is the Thévenin resistance * the shortcircuit current. The open circuit voltage, Voc, is shown above. If we we ...

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.
