... Answer: zero! This is a tricky one! Initially, there is no charge q on the capacitor so no VC = q/C. Prior to opening the switch, the capacitor is discharged, because the inductor acts like a short (a wire) which discharges the capacitor. When the switch is opened, current begins flowing through th ...

Example Equivalent Circuit Problem
... Note that because the upper terminal for the voltage vW is inside the equivalent circuit, and not present outside the equivalent circuit, it is not possible to label vW on the diagram after replacing the equivalent circuit with the 3.49[kW] resistor. Note, however, that since the voltage vX can be l ...

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.
