Glass, a certain kind of metal for thefilament(if incandescent), sufficient wiring for the bulb, a mountable surface for the bulb to attach itself to, insulation (again, for incandescent). And, forfluorescent bulbs, a certain type of gas on the inside in the place of the filament.

Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
What is a light bulbs raw material?
Glass, metal, inert gas.
Will adding light bulbs to a parallel circuit causes all of the light bukbs to shine less brightly?
No. In a parallel circuit, the resistance gets cut in half, so logically the bulbs would do the opposite and get brighter.
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.
Why are light bulbs known as resistors?
The light bulb filament is made of a material fundamentally like the material used in resistors.
Is carbon wire still in light bulbs?
Modern light bulbs are made of tungsten wire.
What type of light bulbs do modern table lamps use?
Modern table lamps use all sorts of different light bulbs. Most commonly one can find standard 20 watt to 250 watt light bulbs in modern table lamps.
Is the material inside a light bulb a conductor or resistance?
It has high resistance.
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

What two circuits one series and one parallel use light bulbs to provide resistance. Both circuits have the same number of light bulbs?
Series circuit gives higher resistance compared to parallel circuit.
How resistence important?
Resistance is important because it is what resists the flow of charge and can give off heat. Light bulbs use resistance to give off their light since the light is from the heat given off from resistance.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
What is a light bulbs raw material?
Glass, metal, inert gas.
A material that transmits nearly all the light in a ray because it offers little resistance to the light is?
A material that transmits nearly all the light in a ray because it offers little resistance to the light is called transparency.

What so good about light bulbs?
without light bulbs the modern world would be plunged into darkness. Light bulbs can not only produce light, but also heat, preventing the death of some pets, such as geckos, snakes, and lizards.
In a series circuit when adding light bulbs does the current change?
Yes. The current is inversely proportional to the resistance. I = V / R where I is current, V is voltage, and R is resistance. Adding light bulbs adds resistance. Current is constant throughout a series circuit; it doesn't change no matter what. Voltage changes.
