How long does it take for a 100-watt light bulb to consume 100 watts of energy?

it will take more than100 watts until the filament reaches operating temperature
so perhaps a second to get as low as 100 watts .
then 100Watts there after until 300 hours pass then 0 watts
if you mean 100Watt hours then the answer is 1 hour and the hour will cost about a penny

∙ 9y agoIt doesn't work that way. The watt is a unit of power, not a unit of energy. Power means energy per unit of time; in this case, joules / second, where joule is the unit of energy. It is like the "speed" (or rate) at which energy is consumed.

How many watts does a light bulb use per week?
Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
How much power does this unit consume?
an 1100 watt microwave wil generaly consume aproximatly 3.0 wats when not in use and close to 1100 watts while in use, the internal light while the door is opn will consume about 32.4 watts. There are 1000 whats in a Kilowatt hour.
How many watts does a 12 volt transformer consume to power a 50 watt down light?
If by "consume" you mean "waste as heat", that would depend upon the design of the transformer, but would typically be a few watts of heat loss.
How many joules of light energy are in 1440 watts of electrical energy?
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

Which uses more watts a 100Watt light bulb or a toaster?
That depends entirely on the toaster, but in general, most toasters use over 1,000 watts.
How much power in watts will an led bulb consume if its energy is 6 joules?
Joules (energy) are not equivalent to Watts (power).If something converts 6 Joules every second, it is 6 Watts. If it takes ten seconds to convert 6 Joules, its power is 0.6 Watts.Multiply the Watts by the seconds to find the Joules.CommentYou do not 'consume' power. Power is simply a rate; you cannot consume a rate! You consume energy; the rate at which you consume it is power.
A couch potato might consume 6 million Joules of energy in a day What is this rate of energy consumption in watts?
Rate of energy= 69.4 watts.
How many watts does a light bulb use per week?
Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.
What is the total wattage of 3-20 w light bulbs?
Three 20 watts bulbs will consume 60 watts.
How many watts does a 18 watt floresent light bulb consume?
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
60-watt light bulb in jouls?
A Watt is a Joule per second. Joules measure energy and Watts measure power, which is the rate of energy used. Therefore, if you use a 60 Watt light bulb for 10 seconds, you consume 600 Joules.
The power of the light bulbs is measured in what?
The amount of power they consume is measured in watts. The amount of light they put out is measured in lumens.
How many watts CFL do you need to grow 1 marijuana plant?

How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
