Transformers - Mt. San Antonio College
... • This means the wires can only handle so much combined voltage and current before they break down. • Transformers usually have their power rating printed right on them. • A typical transformer could be labeled 24VAC, 3A, 60Hz. This implies a 24Vrms secondary, a 3A maximum secondary current and 60Hz ...

This means that their voltage remains constant and they can supply any current we wish if we connect the correct resistance. In most cases these are good assumptions, but if you take a small battery and connect ...

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.
