Phy 440 Lab 8: Bipolar Transistors I
... You can make a crude test of a transistor by using the diode test option on a multimeter. This option sets the terminals of the multimeter so as to forward bias the junction and then to read the voltage across it. For a silicon transistor like the 2N2219 you expect to find a forward voltage of 0.6 o ...

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.
