What is measured in units of lux?

Lux is a measurement of light, the brightness at source. The higher the number the brighter the sourceIllumination, the light output of a light bulb.


What effect would a pencil have on the brightness of a bulb?

A pencil has nothing to do with the brightness of a light bulb.


How does the amount of magents and wire affect the brightness of a light bulb?

The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.


Does a 9 volt battery light a light bulb?

Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.


Why won't a three way lamp switch work with a wall controlled outlet?

Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.

How are light bulbs measured?

Brightness of a light bulb depends on the power, current, resistance and size of the filament. Lumens is the unit of measurement for the brightness of a bulb. A bulb has more brightness if there is more power and current. Greater the resistance, less is the brightness.

Are ordinary light bulbs rated in terms of luminosity or brightness?

Yes, ordinary light bulbs are rated in terms of luminosity (which is generally understood as a measurement of brightness) AND voltage AND current. And physical size AND type of base (screw in, bayonet and which size?).There are many parameters that a light bulb can be rated by.


How does area of the circuit affect brightness of bulb?

if light is low it can cuase the bulb brightnees.


Is watts the measurement of a life cycle of a light bulb?

No, the wattage measures only the power the bulb consumes. There are many factors that affect the life of a lightbulb, from its construction to manufacturing process to environmental, etc.
