... large. The total equivalent resistance which the battery sees increases (since bulb 2 is gone, there are fewer paths for the current flow, so less flow, more total resistance.) Since the battery sees a larger Rtot, the current from the battery Itot = V/Rtot is reduced. Less current from the battery ...

... Resistance can be calculated using, R = V/I. The slope of the V versus I, line will also give the resistance, R. For non-ohmic resistances, I versus V is a non-linear relationship, and they have a varying resistance. The resistance at a particular point can be calculated using, R = V/I, where V and ...

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.
