**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 â€¦... 1/12/2016Â Â· 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 calculate watt-seconds- Flash and Studio Lighting**

A Watt is a unit of electrical power, which expresses how much energy (measured in Joules) gets used or transmitted per second. A Volt is a measure of electric potential. It expresses how much energy you get per unit charge, with no mention of time....21/03/2010Â Â· Suppose that all the energy from a 100-watt light bulb came in the form of photons with wavelength 600 nm. a. Calculate the energy of a single photon with wavelength 600nm. b. How many 600 nm photons must be emitted each second to account for all the light from this 100 watt â€¦

## How To Find Watt Per Second

### To answer the initial question â€” what is a watt second â€” 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.
- 12/02/2008Â Â· 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".
