How many joules are used to produce light in a 10 watt light bulb?

'Power' is a rate; it simply tells us how much energy is being consumed per unit time. In SI, a 'watt' is a special name given to a 'joule per second'. So a 10-W lamp is consuming energy at the rate of 10 J/s (joules per second).
It is incorrect to say that 'power flows'. It's energythat 'flows', power simply tells us how quickly energy flows. You can think of 'power' as being equivalent to 'speed'; you would never ever say that 'kilometre per hour' flows, so you can't say that a 'watt' flows!

Could batteries light a light bulb?
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).
How many hours did Edison light bulb stay lit?
66
How many joules does A 100 watt light bulb consume in 24 hours?
You need to understand the difference between power - as in watts - and energy - as in Watt hours. Watts/kiloWatts only tells you what it's doing at the moment, at that very instant. While Wh/kWh tell you the sum of what it's been doing over a certain time. 1 kW = 1000 w So 100 W / 1000 W = 0.1 kW As soon at the light is turned on, the lamp starts to use energy at the rate of 100 W = 0.1 kW If you leave it on for 24 hours it will have used up 0.1 x 24 = 2.4 kWh
How many wires are normally connected to a double filament light bulb?
5
How many Irish men does it take to change a light bulb?
It takes 201. 1 to hold the light bulb and 200 to turn the house.
How many joules are saved by a energy efficient light bulb?
there are 100 joules in an energy efficient light bulb 75 joules go towards the light and 25 joules go towards the heat
Does a 150 watt bulb do 150 joules of work?
Every second a 150 Watt bulb converts 150 Joules from electricity into heat and light. The number of Watts tells you how many Joules pass per second.
How many joules does a 40 watt ight bulb convert in 10 seconds?
Four Hundred Joules
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).
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.
How many btu's of heat are produced by a T8 fluorescent lamp?
Almost 90 % of electrical energy provided to an incandescent light bulb goes as heat and rest as light. A 100 Watt bulb puts out 100 Joules of heat per second. So - for one minute it would put out 6000 Joules (100 Watts X 60 seconds). 1 BTU (British Thermal Unit) of heat = 1055.056 Joules. So a 100 watt bulb, burning for one minute would put out 5.68 BTUs of heat. ( 6000 Joules / 1055.056 Joules) = 5.68 BTUs. Same bulb burning for one hour would generate 341 BTUs of heat.
How many parts are there to a light bulb?
their are 8 parts to the light bulb
How many volts of electricity does a 60wat light bulb use if left on for 15min?
You can't calculate how many volts with that information; you could calculate the energy - 60 watts for 15 minutes is equivalent to 54,000 joules.
How many light bulbs to light a big light bulb?
It depends how big the light bulb is to be honest
How many philosophers does it take to change a light bulb?
Define "light bulb"
How many volts lamps use?
it varys from light bulb to light bulb.
What does the the difference between a watt and a watt light bulb describe?
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
