What is given off a light bulb?
Heat and Light
The heat given off by a light bulb is thermal energy. The light itself is electromagnetic energy. All chemical energy is potential or stored energy.
mostly light and heat (infrared)
It depends what it is... if you were talking about a light bulb for instance.. more heat energy is given off than light.
Assuming you mean the type that was invented by Thomas Edison, it is the Incandescent Bulb. Light is given off by a coiled Tungsten filament that is heated by an electric current flowing through it. The amount of light given off is rated in Lumens, but most generally the consumer relates it to "Wattage". The higher the wattage the more light given off.
From the electric current that powers it.
60 watts means the same as 60 joules per second. This is the energy used; all of the energy will be given off by the light bulb (but not all of it will be radiated as visible light). 60 watts means the same as 60 joules per second.

it could be no it is not it depends on its usage.
what is the disadvantages of thelightbulb? The biggest disadvantage of the light bulb is the heat that is given off by the bulb. On most bulbs this heat is wasted energy that is paid for and it is not being used. Another disadvantage is the fragility of the bulb in a vibration environment. When the light bulb is on, the filament can break very easily with the slightest vibration.
In an incandescent light bulb the wire that gives off the light is called the Filament.
All other things being equal it will melt faster near the light bulb due to the heat being given off
The high resistance of the filament in a light bulb causes the light bulb to heat and give off light. :)
A light bulb is not a change in and of itself but the process by which it gives off light is physical. While an electric current causes a given component of the bulb to glow (it may be the filament of an incandescent bulb or the vapor in a fluorescent one), but that substance does not change its chemical identity.
Yes. Generally the higher the wattage, the greater the heat it gives off.
Light energy leaves when light bulb is off. No electrical energy is supplied.
no because it doesn't take up any amount of space
The filament is the one that throws off light in the bulb.
a normal light bulb gives off more light
To change a light bulb for a fog light on a 1987 Trans AM, the engine must be switched off. Once the engine has been switched off the light bulb can then be changed.?æ
How about, it gives off light.

The filament in the bulb gives off light.
If you mean a light bulb, it means someone got an idea or they finally understand an idea. "The light bulb went off in his head" But it really should be that it went "on" not "off". The "off" comes from the way a light of a flash camera comes on and off.
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
The w means watt. It is a unit of measurement that quantifies the energy given off by the globe when it is switched on.
Say it is a power circuit, a light bulb is bright from the battery, flowing through the wires and the light bulb. There is a switch controling the power that goes through, so if you switched the off switch off, the power will no longer be flowing through(the light bulb wouldn't be bright any longer).

What is a circuit that allows one light bulb to remain lit while another connected bulb stays off is called?
The question is ambiguous, however one possibility is a parallel circuit, which would permit one light bulb to remain lit while the other light bulb was switched off. By contrast, if the light bulbs were connected in a series circuit, switching one light bulb off would cause both lights to go off.
Its the light given off when you roast (of fry or even casserole) any element. Like in a light bulb glowing, not all the wavelengths of light are given off equally. By looking at what frequencies are there and which are missing you can tell which element you are looking at. You can tell what a distant star is made of using the same principle.
Open switch bulb go off, close switch bulb go on.
It is dependant on whether the switches are in wired in a parallel or series configuration. If the switches are wires in parallel then both switches would have to be off to turn the light bulb off. Either switch could turn the light bulb on. If the switches are wired in series then both switches would have to be on to turn the light bulb on. Either switch could turn the light bulb off.
an incandescent bulb
pop off the lens and remove bulb
A laser is a parallel light source which means that it has effectively infinite object distance. a lightbulb radiates light in all directions. what other differences are you interested in?
fluorescent light bulbs
light and heat
You can replace the dome light bulb in a 2002 Chevy Cavalier by first prying the dome light cover off of the light. Then, remove the bulb and replace it by twisting the bulb from the socket.
No, more than 95% of the energy used by an incandescent bulb is given off as heat. They are incredibly inefficient.
By popping the light cover off and then figure out in your owners manuel how to remove the the bulb.
It is a load that gives off light when current heats up filament in an incandescent bulb.
How do you change the light bulb in the trunk of 2002 Cadillac DeVille you can not get the plastic off to get to the bulb?
The plastic cover will pop off. Then remove bulb.
Technically the bulb does not light, it is but a housing for the filament and electrodes. It is the filament that gives off the light as it is heated by the electricity passing through it. The bulb helps to scatter the light in equal proportions.
The filament in a light bulb causes the light bulb to heat up and give off life.
THe light bulb emits light while in the process heat in the infrared spectrum is emitted.
This light bulb does not produce heat and that is why it is given that name
i have just tried this (and given up). it seems you hve to take the entire light unit out and bumper off. apathetic
