Does a light bulb give off light because the wire inside it is an insulator?

In a physical definition you could say that, as it is insulated from your touch due to the glass globe surrounding the live filament element. That said the tungsten element is a resistor. It is the resistance of the element that makes the lamp glow. Depending on the strength of the resistance is what varies the brightness of the lamp and this is how the wattage of the lamp is determined.

What is the wire inside a light bulb called?
filament
What parts of a light bulb are conductors or insulators?
The conductors are the two wires you see supporting the filament. The glass supporting all this is an insulator. The metal ring around the base and the very bottom of the bulb conduct the electricity into the bulb. The plastic between them is an insulator. --- In incandescent bulbs, the filament of the bulb is a conductor, but has a high resistance to the flow of current, causing it to heat up and glow. In fluorescent bulbs, the gas in the tube resists the flow and is ionized. The ultraviolet photons that it gives off cause the inside of the tube (coated with phosphors) to glow.
Is an light bulb charge of electricity?
Well if you brought a light bulb friom a shop then no but when you put the light bulb in the the thing on where it goes then yes it does because the light is on the you are going down on your power
What light bulb number for a 99 Toyota Camry?
need more info. which light bulb? there are a hundred lights inside and out for a camry.
Which color of light cause bean plants to grow faster?
It will have the same effect as a flourescent light bulb. Its basically the same light. On a white flourescent light bulb, the inside has been frosted white to give off a white light. Without this coating, its the same as a black light. The uv rays are the same.
What is the insulator in a light bulb?
Glass is the insulator in a light bulb. The base has a heavy piece of glass to separate the ring from the center, and there is a glass support inside the bulb to hold up the filament and separate the wires going to the filament.
What does the insulator do in a light bulb?
The insulator in a light bulb prevents us from getting an electric shock.
What causes a light bulb to go out when tightened in socket?
Because when a light bulb is tightened the stuff inside squashes then snaps, causing it to blow.
What will happen if a glass of a light bulb is connected to a battery?
Nothing, glass is an insulator.
Is a light bulb evacuated?
Yes, the inside of a light bulb is a partial vacuum.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
What gas is inside a light bulb?
The kind of gas that is in a light bulb is called Argon.
Is a glass bulb a conductor or insulator?
Insulator.
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
What temperature does a filament inside a light bulb reach?
Answer:The filament inside the light bulb reaches over 3000 degree Celsius.
What is the filament inside a light bulb?
Tungsten
How do you produce light bulbs in CO2?
You do not. CO2 has nothing to do with the creation of a light bulb. A typical incandescent bulb has a vacuum inside. No light bulb uses CO2.
