... Step #3. Now that we have two boxes vertically, we can solve for the unknown values in the total column. Using Ohm’s Law we can now determine the unknown current values. The formula for finding current is current equals voltage divided by resistance (I = E/R) or 100/150 = 0.666. Step #4. Since curre ...

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.
