What happens during a light bulb burning out?
A light bulb works by passing electricity through a long, thin piece of metal that is called a filament. The electricity heats up the filament much like an electric stove heats up its elements. The heat, through black body radiation, causes the filament to emit light. But, the heat also stretches and thus weakens the filament. Over time the weakening will break the filament along the heated portion and this is called "burning out" in common language.
How does the filament in a light bulb work?
it is made of tungsten and is a resistor when current flows thru it it heats up and glows
What energy transformation occurs when a battery powered flashlight is switched on?
Chemical energy is changed to electrical energy. Electrical energy heats the filament of the bulb, changing to heat. The hot filament glows, giving off light
How heat gets from the filament to the kernel?
Electric current passes through a filament and heats up the filament which then emits light. The heat is a waste product in this case because all the work being done doesn't convert to the desired product, which is light. Light sources like LED or fluorescent can give out as much light with less heat and are therefore more efficient.
Sentence with filament?
Filament was made from plastic. The filament was very stable and smooth.
What heats up the filament in radiology machines?
The Rotor!
Why do light bulbs have the coil in the middle?
That is the filament. Electricity traveling through the filament heats it to the point of glowing brightly - that is the light bulbs "light".
How do tungsten-halogen bulbs generate light?
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
How were electrons produced from the cathode ray ube?
Filament heats a cathode until it gives off electrons.
What is the purpose of the filament inside the light bulb?
The filament is a special metal composition of tungsten that conducts current and heats up and emits light as a result of the current and its internal resistance.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.

Why are electric light bulbs hot to the touch?
This is the case in any bulb that heats a filament. The current flowing through the filament generates heat which radiates photons and produces the light you see.
What is the property of the filament that makes it light up when electricity flows through?
the simple answer is resistance, the filament is a very fine wire (usually tungsten) that heats up and glows when power is applied

What is filament coil?
it is the coiled wire that heats up and gives off light in a incandescent (ordinary) light bulb.
