Light bulbs are of different types: incandescent, fluorescence, light-emitting diode. Generally, the answer is heat! In common household current, AC, the current switches direction many times per second. As the incandescent bulb heats up, it twists one way and then the other. These mechanical gyrations will eventually break the filament that heats up and supplies the light. Etc.

How many batteries does it take to burnout a light bulb?
The number of batteries needed to burn out a light bulb depends on the type of battery and the power rating of the light bulb. Typically, for a standard household light bulb (60-100 watts), one high-power battery or two to three regular batteries might be enough to burn it out due to overload. However, attempting to intentionally burn out a light bulb can be dangerous and is not recommended.
Why do you need electricity to light a light bulb?
Electricity is needed to light a light bulb because the flow of electrons through the filament inside the bulb generates heat and light energy. This energy causes the filament to emit light, thus illuminating the bulb. Without electricity, there is no source of energy to power the light bulb.
Why is a light bulb sealed?
A light bulb is sealed to prevent air from entering the bulb, which can cause the filament to burn out quickly. The vacuum or inert gas inside the bulb helps to preserve the longevity of the filament and ensures consistent lighting performance.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
Why did people think the light bulb was not going to work?
People initially thought the light bulb wouldn't work because they believed the wire filaments would burn out quickly, the vacuum inside the bulb would not be maintained, and that electricity would be too expensive to produce light.
How many days the light bulb lasted?
Takes 300 hours for the average light bulb to burn out
What does the exclamation light mean on the dashboard?
You probably have a light bulb burn.
What won't burn over a light bulb?
glass
Does a light bulb glow brigther with a thin or thick wire?
A thinner wire in the bulb increases resistance and causes the metal to " burn hotter" converting the electrical energy into thermal and radiant energy
What causes a light bulb not to work?
Bad bulb, no power, no ground.
What are the causes and effects of incandescent light bulb?
Because of the creation of the light bulb you could Illuminate a room without dangerous candles Turn the lights on and off quickly It can burn for 40 hours You won't have to replace a lightbulb as often as you replace candles
Is there a scientific explanation to the tiny dots flies make on hanging light bulbs?
Just spots of excrement that the bulb heats and causes to turn dark or burn.
What will happen if you put an Improper bulb in a light fixture?
it will burn
how many days the bulb lasted?
Takes 300 hours for the average light bulb to burn out
Could a light at 110 voltage be used in UK?
The light bulb will probably burn out, if the fuse of the lamp does not burn out first. On the other hand, a lamp with 240V rating can still be used in the USA, but the light will be about half as bright for the same light bulb.
Will a light bulb burn or melt a rubber band?
It depends upon the wattage of the light bulb. The lower the bulb wattage the lower the heat generated by the bulb. A 100 watt bulb should generate enough heat to destroy a rubber band.
What has happened when a light bulb has burn out?
it simply means that a wire from the light bulb is joined or connected to the charged plates of the capacitor.resulting to discharged of the capacitor.
