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 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.

How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
How many joules are there in a kilojoule?
A Joule is a Watt-second (or W=J/s). Therefore, 3.5 kWh = 3.5*3600 kWs = 3.5*3600*1000 W-s = 12.6 million Joules
How many watts in 1 kilowatt?
Killo = 1000. There are 1000 watts in 1 kw.
How many joules are in 59.4 watts?
"59.4 watts" means "59.4 joules every second"
Does a 150 watt bulb do 150 joules of work?

How many joules does the sun release in one second?
It is approx 3.82*10^26 Joules.
How many joules are there in 3kw kettle each second?
Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.
How many kilocaclories of heat does the operation of a 1190 watt hair dryer produces each second?
Watts means joules per second. The device uses 1190 joules of energy every second; most of that will be converted to heat. It is best to use SI units most of the time; in this case, joules rather than calories for energy. However, if you want to convert that, 1 calorie = 4.184 joules; thus, you can divide the number of joules by 4.184 to convert it to calories.
10 kw equals how many joule per second?
10,000 joules per second.
How many joules are in a refrigerator?
For every joule of electricity we put into a refrigerator we can extract up to 25 joules of heat from its contents.
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 units per hour utilized by a 45kw motor?
watt (w) means joules per second. kW (kilowatts) means thousands of joules per second. Multiply that by 3600 to get the joules used per hour.

One kilowatt equals how many btu per hour?
A BTU is about 1055 joules. A kilowatt is 1000 joules/second, so it is 3,600,000 joules/hour. Dividing that by 1055 joules gives you the equivalent of about 3400 BTU/hour.
How much energy every second would a 100 watt light bulb use?
100 Joules = 100 watt second = energy1 joule = 1 watt second
