!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!


NO NO NO NO NO---there is no time involved.
Back in the 70s when I taught electricity and electronics (for 10+ years), the watt always referred to the amount of current x the voltage used over time.

An Ampere being one coulomb. (A coulomb is equal to exactly 6.24150962915265 ×10 to the 18th elementary charges.).
Or, a whole big bunch of electrons!!

Here ya go!
Watt - Wikipedia, the free encyclopedia
The watt (symbol: W) is the SI derived unit of power, equal to one joule of energy per second. It measures a rate of energy use or production.
