... In the UK, generating companies are required to provide customers with a voltage between 216V and 253V. The average voltage across the UK is 242V, but levels can fluctuate significantly throughout the day on each site. Across Europe, the standard voltage has been historically 220V. As a result, most ...

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.
