Switching Low Offset Voltage
... Designing a 2 pole vs a 1 pole low offset voltage relays are quite different. Generally coil resistance must be as high a value as possible. The higher the coil resistance the lower the power generated across the coil. The lower the coil power the lower the heat it produces. This means we must caref ...

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.
