WebThe SI unit of power is the horsepower A person is limited in the total work he or she can do during a limited period of time by the rate at which energy can be transformed. The SI unit of power is the watt. A person is limited in the total work he or she can do only by the total energy required. Power is the rate at which work is done. WebWatt 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. cowboys 4th down
