lumen
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.
A pencil has nothing to do with 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.
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
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.
An item called a LUX meter is usually used for the determination of the brightness of a light bulb. It is generally a meter that measures the amount of incident white light.

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.

Then the brightness of the light buld increases.
u see the light bulbs on a series circuit's brightness evolves and the brightness on a parallel's circuit dont
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.
if light is low it can cuase the bulb brightnees.
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.
