... distance. The Sniff-It beeps slowly when close to low voltages, and quickly when close to high voltages. At a distance, a high voltage will cause the Sniff-It A to beep slowly, and to gradually beep faster as the source of voltage is approached. This allows the user to "home in" on the source of the ...

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.
