watt
(a) The practical unit of electric activity, rate of work, or rate of energy. It is the rate of energy or of work represented by a current of one ampere urged by one volt electro-motive force; the volt-ampere.It is the analogue in electricity of the horse power in mechanics; approximately, 746 watts represent one electric horse power.Ohm's law, taken as C = E/R, gives as values for current, C and E/R, and for electro- motive force C R. In these formulas, C represents current strength, R represents resistance and E represents electro-motive force. Then a watt being the product of electro-motive force by current strength, we get the following values for rate of electric energy, of which the watt is the practical unit: (1) E2/R -- (2) C*E -- (3) C2 * R.

The watt (symbol: W) is the SI unit of power. It is named in honour of the physicist James Watt (1736–1819).
Definition.
The watt is the rate a source of energy expends or produces one joule during one second, so the same quantity may be referred to as a joule per second, with the symbol J/s. It can also be written as kg·m2·s−3.
It is equivalent to one volt ampere (1 V·A) or 1/746 of a horsepower.
