How the filament is heated?
The filament in a light bulb is heated by passing an electric current through it, which causes the filament to resist the flow of electricity and heat up due to its electrical resistance. The heat generated by the filament causes it to emit light, producing illumination.
Which gas in the air burn's out the filament?
Oxygen is the gas in the air that burns out the filament in an incandescent light bulb. When the filament reacts with oxygen at high temperatures, it oxidizes and eventually burns out.
What heats the filament?
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Why does the filament of a light bulb not burn?
The filament of a light bulb does not burn because it is made of a material, typically tungsten, that has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it. Additionally, the filament is enclosed in a vacuum or inert gas to prevent it from reacting with oxygen and burning up.
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 do light bulbs burn out quickly?
Light bulbs burn out quickly due to the filament inside them becoming too hot and eventually breaking. This is often caused by the flow of electricity through the filament, which generates heat and causes it to wear out over time.
Which gas in the air is needed for a filament to burn?
Oxygen is the gas in the air that is needed for a filament to burn. Oxygen supports combustion by reacting with the material in the filament, allowing it to produce light and heat.
Why do lightbulbs burn out?
They burn out from 1) the rapid heating and cooling of the Tungsten filament, and 2) from the tungsten atoms being released from the metal filament by way of the extremely high temperatures. Eventually the tungsten metal fails and the filament breaks.
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 bulb filament does not burn at high temperature?
The metal will melt if you do that.
Property of the filament that makes it light up when electricity flows through it?
Incandescence. The filament is heated by the electricity moving through it, this causes the filament to heat up, and the heat causes the familiar glow.
How the filament is heated?
The filament in a light bulb is heated by passing an electric current through it, which causes the filament to resist the flow of electricity and heat up due to its electrical resistance. The heat generated by the filament causes it to emit light, producing illumination.
Why the electric bulb does not works if oxidation takes place inside it?
Because the filament will burn, and the filament is the part that produces the light.
Why it is said not to throw water at a glowing bulb?
ts filament will not burn
Which gas in the air burn's out the filament?
Oxygen is the gas in the air that burns out the filament in an incandescent light bulb. When the filament reacts with oxygen at high temperatures, it oxidizes and eventually burns out.
What heats the filament?
The electric current passing through the filament in an incandescent light bulb heats it up. This causes the filament to glow and produce visible light.
Why is the bulb evacuated?
If they were not evacuated of all outside air, the filament will burn up in seconds because the air Will cause Resistance, thus the filament will burn brighter and brigther tyring to burn off the air until it opens. (blown bulb)...
