... This gives R1 = 2 kΩ because V/mA = kΩ. R2’s value is 3 kΩ. For v3 and v4, we know the total voltage across the two is v4 + v3. From the given equation, we know that v4 = 2*v3 because their ratio is 2:1. Set our equation equal to 6 V. So v3 should be 6/3 = 2 V. This means that v4 = vs – v3 = 6-2 = 4 ...

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.
