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.
What else can I help you with?
What is a light bulbs raw material?
Glass, metal, inert gas.
Light bulbs in a series circuit have the same brightness?
If they have the same resistance they will. Kirchhoff's' Law.
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.
What is the maximum voltage of incandescent light bulbs?
The maximum voltage of incandescent light bulbs is up to about three hundred volts. They can also go down as low as 1.5 volts. Incandescent light bulbs are the least efficient lighting system. More modern methods like flourescent lightbulbs are far more efficient.
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.
Is carbon wire still in light bulbs?
Modern light bulbs are made of tungsten wire.
What wire gives of light in a bulb?
Typically, a tungsten filament wire is used in light bulbs to produce light when an electric current passes through it. The wire heats up and produces light due to the resistance of the material.
What materials are light bulbs made out of?
Light bulbs are typically made out of glass, metal, and a filament material such as tungsten.
Do the same wattage light bulb have different resistance?
Yes. The resistance of a globe depends not only on the wattage of it but also on the voltage. A 12 V Globe would has a quarter the resistance of a 24 volt globe for the same wattage. (when alight)
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.
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.

Is the material inside a light bulb a conductor or resistance?
It has high 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.
In a series circuit with multiple light bulbs attached to a battery why are you seeing the light bulbs closest to the battery are brighter than those bulbs further from the battery?
The light bulbs closest to the battery appear brighter because they have less resistance in the circuit compared to the bulbs further away. As current flows through the circuit, it encounters resistance from each component, which results in a potential drop. The bulbs further away experience a larger voltage drop due to the increased resistance, leading to dimmer illumination.

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.
