... Hold the motor carefully so you will not be hit by the fan blades. Start with Vin = 1 V and gradually increase Vin until the motor begins to turn. You might need to give the fan blades a small push to get it going. Be careful not to increase the voltage more than you need; the small resistors will d ...

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.
