... Describe the scope of the work to be undertaken: We supplied 10 volts into the amplifier then we read the values of the components by using a multimeter to find out what was the fault in the circuit. After confirming faulty parts, finally we replaced those bad parts with new ones. (This task should ...

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.
