WebOne joule per second is equal to 0.001341022 horsepower. Watt : The watt is a unit for power, is one of SI Units. Its name is in honor of the Scottish engineer James Watt, the eighteenth-century developer of the steam engine. The unit symbol for watt is W, defined as one joule per second, measures the rate of energy conversion or transfer. WebElectrical Power. 1 watt (W) = 1 joule/second (J/s) So if 1 watt = 1 joule per second, it therefore follows that: 1 Joule of energy = 1 watt over one unit of time, that is: Work equals Power multiplied by Time, (V*I*t joules). So electrical energy (the work done) is obtained by multiplying power by the time in seconds that the charge (in the ...
