... You can verify for yourself that if each individual resistor has a value R, the equivalent resistance of the arrangement above is also R. The advantage in this situation compared to using a single resistor of value R is that while the total power dissipation is the same, it is now divided between fo ...

If the line OP is drawn from the origin, tangential to the internal characteristics, the gradient of this line will give the minimum value of the external load resistance for which the generator will excite on load. This resistance is known as critical load resistance. If the resistance of external ...

Potential difference in circuits notes
... The resistance of a wire does not change with its temperature. The current that passes through it is therefore directly proportional to the voltage across it. This means that if the voltage is doubled then the current doubles too. The shape of an I-V graph for a filament bulb is caused by the fact ...

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.
