A light bulb glows because of a very fine wire inside the glass bulb called a 'filament'. When an electrical current is put through the filament, assuming the voltage is high enough, it will begin to heat up and glow because such a small wire cannot handle the flow of electrons and has to discharge them through heat and light. Also if you put to much voltage in it will heat up the filament too much and melt it. Incandescent (filament) light bulbs fail over time because they slowly lose small amounts of wire until the filament breaks and stops glowing.

Unfortunately, most filaments designed today don't last near as long as the bulb is rated at. Just put a dated replacement sticker on a light bulb and see when the next time you replaced it how long it went. You will be surprised.

What do the support wires do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
What is the name thin wire inside a light bulb?
a filament
How will a single burned-out bulb affect the strings of lights if each light is attached to its own wire?
If by "its own wire" you mean they are connected in parallel, then one bulb won't affect the others.
What happens to light bulb in a circuit when the wire gets skinnier?
it either blows up or worn out
How do light bulbs generate?
They light up from the piece of wire in the middle of the light bulb. Joseph Swan invented the first light bulb. Not Thomas Edison <<>> Light bulbs do not generate they are classified as a load. Generators generate power by utilizing the magnetic flux of coils in the rotor, cutting coils of wire that are located around the generator's stator.
Which wire used for ordinary light bulb?
In most home wiring circuits, the black wire is used to power a light bulb. The other wire is white and is called the neutral conductor.
Will two batteries and a wire make a light bulb light?
first of all, you need a bulb, a wire, and ONE light bulb. You clip the wire on the battery and touch the wire on the bottom of the light bulb
What is the wire that gives off light in a light bulb?
In an incandescent light bulb the wire that gives off the light is called the Filament.
What is the resistor inside a light bulb called?
the wire in your light bulb is a resistor :)
Where does the energy for a light bulb come from?
it come from the energy source in the middle of the light bulb he clearly asked what type of energy is it?!
What is a wire in a light bulb?
filament
Why it is possible to light the bulb even though only one wire is used?
its the light was not appeared but not all are us a bulb to have possible to the light when it is open they conssume to another part that they..
How can lemon make a bulb light?
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.
How do you make a battery light a light bulb?
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
How would a meter be connected in a circuit too measure the voltage at a light bulb?
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
What do support wire do on a light bulb?
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
