... The voltmeter will read 12 V, since the potential difference across the resistor must be equal to the potential difference across the battery. As we will see later, if there were more than one resistor in the circuit, there would not necessarily be 12 volts across each. The power can be found by P = ...

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.
