... If we set I2 at zero, we can find z11. [math equation] The voltage that crosses the first port is V1. Let’s look at the top node. We can label the current flow through the two resistors as I3 and I4. Based on the Kirchoff Current Law, we know that I1 should be equal to the sum of I3 and I4. [math eq ...

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.
