Current passing through a special wire like tungsten heat up the wire and create light by emitting photons
The filament inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
no
That part of a light bulb that causes light to light up is called the filament, and it is typically made from tungsten.
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.
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
The filament in the bulb has a high resistance to the flow of electricity. As electricity passes through it, the filament heats up and begins to glow, giving off the visible light you see.
A fused bulb does not glow because the filament of a fused bulb is broken. Since current can't flow through the filament, it can't get hot enough to glow.
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
The filament inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.
Mainly to prevent the filament, the glow wire from burning up.
