The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer .
A watt is a unit of power, named after engineer James Watt, which measures the rate of energy transfer. A watt, in electrical terms, is the rate at which electrical work is done when one ampere (A) of current flows through one volt (V). Formula: W= A* V. Whenever current flows through a resistance, heat results. This is inevitable.
Watt is the unit of power (symbol: W). The watt unit is named after James Watt, the inventor of the steam engine. One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt. 1W = 1V × 1A.
Watt, unit of power in the International System of Units (SI) equal to one joule of work performed per second, or to 1746 horsepower. An equivalent is the power dissipated in an electrical conductor carrying one ampere current between points at one volt potential difference. It is named in honour.

The watt is a measure of the rate of energy transfer over a unit of time, with one watt equal to one joule (J) per second: W = J/s. A joule is the standard unit of energy or work in the SI standard, which defines the joule in terms of kilograms, meters and seconds: J = kg∙m 2 ∙s-2
In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and traditional measures are horsepower (hp), comparing to the power of a horse; one mechanical horsepower equals about 745.7 watts.
Watt is a unit of power, joule is a unit of work and energy, and time is a unit of time. An equation for solving Power, Work and Time is Power = Work ÷ Time, Work = Power × Time, or Time = Work ÷ Power .
