How many watts per year science.answers.com
Watts are a measurement of how many joules of work can be done in one second and are commonly used to indicate how much power an electrical device uses. Kilowatt hours are a measurement of energy and are used to calculate how much work can be done in an hour with one kilowatt--1,000 watts--of power. To determine how much energy an electronic device uses over a period of time, you must …... 1/12/2016 · A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

How To Find Watt Per Second

To answer the initial question — what is a watt second — it is a unit of stored energy, nothing more. Just as engine size will not solely determine a car's efficiency, the amount of stored energy will not be the only factor determining a flash's performance. Choosing equipment based solely on watt seconds will not give a true representation of the equipment's capability.

  • A 4 watt-second flash that is 100% efficient will put out the same amount of light as a 400 watt-second flash that is 1% efficient. "Effective watt-seconds" are ill-defined as well , so are basically just as useless as watt-seconds.
  • 12/02/2008 · In terms of energy consumption, a 1000 watt bulb burning for one second will consume 1000 watt-seconds. But the efficiency of different technologies varies dramatically. Tungsten lights are dreadfully inefficient, producing a small amount of light and a large amount of heat.

  • The watt-second is the energy equivalent to the power of one watt sustained for one second. While the watt-second is equivalent to the joule in both units and meaning, there are some contexts in which the term "watt-second" is used instead of "joule".
