How to Converter energy in joules (J) to Elétrico power in watts (W).
You can Calcular watts from joules and seconds, but you can't Converter joules to watts, since joule and watt units represent different quantities.
The power P in watts (W) is equal to the energy E in joules (J), divided by the Tempo period t in seconds (s):
P(W) = E(J) / t(s)
So
watt = joule / second
or
W = J / s
What is the power consumption of an electrical circuit that has energy consumption of 90 joules for Tempo duration of 3 seconds
P(W) = 90J / 3s = 30W
