... To find values for RA and RB I need to consider what preferred values are available. I chose a 3.6kΩ resistor for RA, which then left me with RB as 20kΩ. I connected up these values to my astable circuit and connected a digital frequency meter to the output. When I connected the battery, the frequen ...

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.
