Alternating Current Applet Activity
... The root-mean-square (rms) value of an alternating current (or voltage) is that value of the direct current (or voltage) that dissipates power in a resistor at the same rate. In this activity you will determine the rms voltage of an ac resistor circuit and use it to show that its equivalent dc value ...

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.
