I would have to guess, 100 watts. Power consumed is equal to P I E. P = Amps (I) X Volts (E). Power is measured in watts, or typically, as read on your energy bill, Kilowatts (kw, where 1 Kw = 1,000 watts). So, 100 watts/120V (which is the typical American system) = 0.833 amp (I). Your typical power meter, by which the power company reads your monthly bill, measures amps. Also, 100 watts is 1/10 Kw, or 0.10 kw/hour
Answer
First of all, you do NOT consume power; you consume energy. Energy is measured in joules, so power is measured in joules per second, which is given a special name: the watt.
So there is no such things as 'watts per hour', as this would mean 'joules per second per hour' which, obviously, is nonsense!
So, your question should ask, "How much energy is consumed by a 100-W lamp in one hour?" Well, if one watt represents one joule per second, then the lamp will consume 100 x 60 joules in one minute and, therefore, 100 x 60 x 60 joules in one hour. That is, 360 000 joules.
Electricity companies usually measure energy in kilowatt hours, rather than in joules. A kilowatt hour is defined as "the energy consumed, in one hour, at a rate of one kilowatt'. You can think of a kilowatt hour simply as being a very big joule! Since 100 W is 0.1 kW, we can therefore say that the lamp must consume 0.1 x 1 = 0.1 kilowatt hours during a period of one hour.

Appliances, such as your lamp, don't 'consume' power; they consume energy. Their power rating merely tells you the rate at which they consume energy. '100 watts' means that your lamp consumes 100 joules of energy every second it is operating.
So, over a period of one hour, your lamp will consume 100 x (60 x 60) = 360 000 joules of energy.
To complicate matters, however, electricity companies usually measure the energy their customers consume in kilowatt hours, rather than joules (a kilowatt hour is equivalent to 3.6 million joules -in other words, it's a 'big' joule!). A kilowatt hour is the amount of energy consumed, over a period of one hour, at a rate of 1000 watts.
To calculate how much energy, in kilowatt hours, your lamp consumes, you must multiply its power in kilowatts (i.e 100/1000) by the number of hours it operates (1), so your lamp consumes 0.1 kilowatt hour. If you know how much your utility company charges, per kilowatt hour, then you can figure out the cost of running your lamp.

∙ 11y agoTo answer this question you need to state what your utility company charges you per kWh. It should be stated on your monthly electric bill. When you find this value multiply it by .100 which is how many kilowatts a 100 watt light bulb is equal to.

∙ 9y agoThe energy is 100 watts times 60 seconds: 6000 watt-seconds, also called Joules. Most of the energy is emitted as heat.

Does a light bulb give out heat and sound energy?
An incandescent bulb in an AC circuit does give off both heat and sound energy; the heat because the filament is hot, and the sound because the varying voltage results makes the filament vibrate. Generally it's not a very LOUD sound, but bulbs which are about to burn out often emit a noticeable buzzing.
Why si and ge does not emit light?
energy levels wrong.
Light energy travels in electromagnetic waves How do electromagnetic waves emit energy?
Through Radiation
What type of energy does an element need to absorb to emit light?
Many different types of energy can do this. Heat will cause anything to emit blackbody radiation and if there is enough heat the blackbody radiation will overlap the visible light spectrum and the object will be incandescent. To emit light as a narrow spectral line requires raising electrons in the element to higher energy orbitals and allowing them to fall back, emitting photons. The type of energy that can do this can be of many sorts: light, chemical, electrical, etc.
Do galaxies emit light?
Yes galaxies emit light
What is the difference between a LED light bulb and a regular?
a regular light bulb emits about 80% heat energy and only 20% light energy, whereas leds emit about 70 % light and 30% heat
Does a light bulb emit carbons when used?
the electricity used to power the light bulb emit carbon dioxide
What does a white light bulb emit?
light and heat
What happens to the energy wasted in a light bulb?
electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see.Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.
What energy trasnformations occur in a incandescent light bulb?
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.
How is eletrical energy converted in light energy?
In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light.In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels.

Atoms emit energy as light when?
Atoms emit energy as light when electrons move to a lower energy level
When 60 W means that W joules of energy are transferred into the bulb each second. In use how much energy is given out by the bulb each second?
The light bulb will use electrical energy at the rate of 60 W (60 J/s), and it will emit that energy, also at the rate of 60 W.Note that in any real light bulb, only part of the energy is emitted as visible light. The remainder is mainly heat.
What is the use of bulb in the circuit?
To emit the generated light?

How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
What type of energy does a light bulb emit?
Mainly heat and light. Heat is carried away through convection, but also radiated away as infrared light, a kind of electromagnetic wave (as is light).
