So the inverting terminal voltage should be equal to that of the non inverting terminal. That is 2V. The input currents should b ...

... Usually, the input is known, but the output is unknown. So suppose that we know the output -- 1V -- but not the input, which we’ll call xu. We’d say that the output is k*input So the proportionality constant is 1/(xu). Find k by analysis of that circuit. We can then use k to find the output when giv ...

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.
