The watt (symbol: W) is the SI derived unit of power, equal to one joule of energy per second
1 joule per second= 1 watt
10 joules per second = 10 watts
100 joules/second = 100 watts.
26.25 Joules per second
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.
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".
40 Joules, I think, as the formula for Watts is Joules/Second = Joules per second 40 Watts should equal 40 Joules per one second...
11 watts = 11 joules per second(440 joules) / (11 joules per second) = 40 seconds
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.
Voltage is electromotive force, in joules per coulomb. Power is energy transfer rate in joules per second, also known as watts.Not asked, but answered for completeness sake, and also to show the relationship between voltage and power, current is charge transfer rate in coulombs per second. So, if you multiply voltage (joules per coulomb) by amperes (joules per second) you get watts (joules per second).
1 joule per second= 1 watt
10 joules per second = 10 watts
10 joules per second = 10 watts
1 watt = 1 joule per second1 kilowatt = 1,000 watts5 kilowatts = 5,000 watts = 5,000 joules per second
10,000 joules per second.
Watt means joule/second, kW (kilowatt) means kilojoule/second, i.e., thousands of joules per second.
100 joules/second = 100 watts.
