WebMar 28, 2014 · The SI unit for energy is the joule (J). 1 J = 1 N⋅m. Power is the measure of how much energy or work is used per unit time. Power = energy time The SI unit of power is joules per second (J/s) or Watts (W). In summary, 1 … WebIt can also be expressed as; Watt = Joule / second or W =J / s For example; If the energy consumption of an electrical circuit is 80 joules and takes 5 seconds, what will be the power consumption? Solution P (W) = 80 J / 5s = 16 watts The calculations are simple and only require the units to be entered in their appropriate cells. The output ...
