How many joules are needed to run a 60 watt light bulb for 1 minute?

1 Watt means 1 Joule per second, so 60 watts means 60 Joules per second. A light bulb that burns energy at that rate for 3 seconds uses 180 Joules.

AnswerSince power is the rate of doing work, i.e. P = W/t, then
W = P t = 60 x (1 x 60) =3600 J
(where:
W = work done, expressed in joules
P = power, expressed in watts
t = time, expressed in seconds)

0.06 kilowatt-hour
(60 watt-hour) x (3,600 sec/hour) = 216,000 watt-seconds
216,000 joules

What is the heat generated with a 40Watt bulb when its for 2 hours?
Let's assume that this is an incandescent bulb with a light efficiency of 35 percent ... i.e. 35 percent of the electric power it consumes is converted to light, and the other 65 percent becomes heat, which the bulb then dissipates into the room. So the bulb is dissipating heat at the rate of (0.65 x 40) = 26 watts = 26 Joules per second. 2 hours = (2 x 3,600) = 7,200 seconds 26 joules per second x 7,200 seconds = 187,200 Joules of heat
In 1879 this invention Thomas Edison burned for 13 hours?
The light bulb. The light bulb. The light bulb.
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
If a light bulb is missing in a series circuit will the bulb light?
If one light bulb in a series circuit fails, all the other light bulbs will go out, until the failed bulb is replaced and the series circuit is completed again.If one light bulb in a parallel circuit fails, all the other light bulbs will still work.
What is 60w light bulb?
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
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
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.
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.
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
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 work does a 75 watt bulb do?
In the sense of 'work' as force moving through a distance, a light bulb does none of that. But in the sense that mechanical work is equivalent to energy in other realms, the 75-watt light bulb consumes 75 joules of electrical energy every second, and radiates 75 joules per second of energy in the form of light and heat.
How much work does a 100-watt light bulb do when its lit for 30 seconds?
3000 joules(J)
How much work does a 100-watt light-bulb do when it is lit for 30 second?
3000 joules(J)
How much work does a 100-watt light bulb do when it is lit for 30 seconds?
3000 joules(J)
What is the effiency of 60watt bulb run on a 100joule?
"60 watts" means "60 joules every second". That's what a '60 watt' bulb is designed to consume. If you put 100 joules of energy into a light bulb, 100 joules of energy are going to come out of it, one way or another. Either that energy will be converted into light and heat by the bulb's filament, or else it won't get consumed at all, and it'll come out the other side of the bulb and still be available for use in some other device. So, comparing output energy to input energy is not an effective way to evaluate the efficiency of a light bulb. What you need to do, in order to compare the economy and effectiveness of light bulbs, is to compare LIGHT output to input ENERGY.
