About all I can find on this kind of question is based on using the size of 12x12x8 foot room a 60w filament bulb will raise the temperature of the room approximately 5 degrees Fahrenheit an hour...I was trying to find out after converting all the bulbs in my house to CF bulbs how much of a temperature savings my AC was seeing vs running incandescent bulbs...doesn't see to be a lot of helpful information out there about it.
An incandescent (GLS)lamp / light bulb generates light by running current through a "metal wire" so it glows to emit light. This is a very costly way of generating light, since only 5% of Wattage is generating light, the rest (95%) is emitting heat. If you use a 100W lamp, 5W is light and close to 95W heat is emitted (there are some losses in base, material (absorbed) etc.A CFL - Compact Fluorescent Lamp - generates light by running current through a gas mixture which contains Mercury or a mercury substitute. This effects an ultraviolet radiation that is converted into visual light by a powder on tube walls in the lamp. The effect is that whenever a mercury atom is hit by "current" it emits an energy burst - a quantum - that is like a snowball effect. This way of making visual light is much more efficient (around 80% better), in terms that you only need 20W CFL to generate similar output as the before mentioned 100W GLS.The heat emitted from a GLS is generated both from the tub ewalls - but also from the Gear in base of CFL lamp. Some 28% of Wattage of CFL is light and some 72% is heat.Since the CFL is 20W, the heat emitted is appr. 14W (compared to the 95W of GLS).
When a lamp is turned on in a dark room, firstelectric energy turns into lightenergy, which allows us to see, then becomes thermal energy, which causes the to bulb be hot.
The lightbulb resists the electricity flow that's flowing through it. The electrical energy is converted to heat energy and spreads to the glass of the light bulb.
a lightbulb gets hot because the current passing through it produces heat
Yes, very very hot except for LED lighting.
No. The Sun is much hotter than a light bulb is.
a light bulb gets 4,500 degrees hot
the heated electicty in the fuse
The bulb glows because the filament inside ( made of tungsten) get's so hot that it becomes red and starts emitting light. A little of it's heat is also radiated to the glass of the bulb and that's what makes it hot. But it will never get hot enough to melt a rubber band.
it makes light
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
As the name implies, support wires support the filament wire in the bulb, The filament, of course is the wire that glows white hot, giving out light
The filament of an incandescent light bulb is actually significantly hotter than lava. Temperatures may exceed 4,000 degrees in some bulbs.
You can't get a wart from a hot light bulb.
The fillement inside the bulb makes it light up. It acts a ressistor and only lets a small bit of electricity through, therefor pressurising the energy which makes it hot and makes it glow.
In simple terms, the current passes through the tungsten filament present in the bulb which causes it to heat instantaneously into red hot to white hot and hence light energy emits.
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.

No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
The bulb contains electomagnetic waves that makes the bulb light.
