... 3. Consider the circuit shown below in Fig 3. V+ = 12 V +/- 1V. The Zener diode has a VZ0= 5 V and rz = 10 Ω. For this question, you can assume that this model is valid for any non-zero reverse breakdown current (IZ > 0). That is, IZK = 0 mA. The resistance R has not yet been specified. There are se ...

... When dealing with resonant circuits it is convenient to refer to the frequency difference between points at which the power from the circuit is half that at the peak of resonance. Such frequencies are known as “half-power frequencies”, and the power output there referred to the peak power (at the re ...

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.
