## watt

(W) [wot]
the SI unit of power, being the work done at the rate of 1 joule per second. In electric power, it is equivalent to a current of 1 ampere under a pressure of 1 volt.

## watt (W),

(waht),
The SI unit of electrical power; the power available when the current is 1 ampere and the electromotive force is 1 volt; equal to 1 joule (107 ergs) per second or 1 voltampere.
[James Watt, Scot. engineer, 1736-1819]

[wot]
Etymology: James Watt, Scottish engineer, 1736-1819
the unit of electric power or work in the meter/kilogram/second system of notation. The watt is the product of the voltage and the amperage. One watt of power is dissipated when a current of 1 ampere flows across a difference in potential of 1 volt. See also ampere, current, ohm, volt.
