Comment convertir l'énergie en joules (J) en puissance électrique en watts (W).
You can calculate watts from joules and seconds, but you can't convert joules to watts, sence joule and watt units represent different quantities.
La puissance P en watts (W) is equal to the energy E en joules (J), divided by the time period t en seconds (s):
P(W) = E(J) / t(s)
Donc
watt = joule / seconde
ou
W = J / s
What is the power consumption of an electrical circuit that has energy consumption of 90 joules fou time duration of 3 seconds
P(W) = 90J / 3s = 30W
