What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.
Why is a filament bulb not filled with oxygen?
Light in a lightbulb is produced by running a current through a wire with a high resistance. This creates a lot of heat, which when hot enough creates light. Imagine heating up a piece of steel until it glows. If the bulb was filled with oxygen, the tungsten filament would burn before it ever got to hot enough temperatures for our light needs. Therefore, we use argon so that while it gets hot, it doesn't burst into flames. Simple, really.
Why does the filament in a light bulb not burn up immediately?
The 'Filament' of a lightbulb is a peice of metal with an unusually high melting
Why does the filament become hot?
The filament becomes hot when electricity passes through it, due to resistance in the wire. This resistance causes the filament to heat up and emit light in an incandescent bulb.
Why does a light bulb filament glow?
A light bulb filament glows when electricity passes through it, causing the filament to heat up and emit light due to incandescence. The high temperature of the filament makes it glow and produce visible light.
How the bulb light?
An electrical current is passed through the high resistance filament in the bulb, causing it to become white hot and so give off light. The inside of the bulb is filled with an inert gas, such as nitrogen, so the filament does not burn up .

Why would the motor die when put in gear after it gets hot?
only if it got hot enough to burn a vacum line which is pretty hot 265 degree and up
Small ground wire from battery gets hot and burn up?
its grounded in more than one place
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 do light bulbs glow?
Light bulbs glow when electricity passes through the filament, causing it to heat up and emit light. The filament is made of a material that has high resistance, which generates heat when the current flows through it. As the filament heats up, it emits light due to its high temperature.
Why the filament in a bulb lights up?
because filaments are generally good conductors of heat , so the filament burns first and then gets heated up and then gives light.
