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 W., Scot. engineer, 1736–1819]

watt 'wät n the absolute mks unit of power equal to the work done at the rate of one joule per second or to the power produced by a current of one ampere across a potential difference of one volt: 1/746 horsepower
Watt James (1736-1819)
British engineer and inventor. Watt's steam engine played a major role in the coming of the Industrial Revolution and came to be used in paper mills, flour mills, cotton mills, iron mills, distilleries, canals, and waterworks. At the end of the 19th century the International Electrical Congress named the watt, the unit of electrical power, in his honor.

n.
the SI units of power, equal to 1 joule per second. In electrical terms it is the energy expended per second when a current of 1 ampere flows between two points on a conductor between which there is a potential difference of 1 volt. 1 watt = 107 ergs per second. Symbol: W.
