How to محول energy in joules (J) to كهربائي power in watts (W).
You can احسب watts from joules and seconds, but you can't محول 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 وقت 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 وقت duration of 3 seconds
P(W) = 90J / 3s = 30W
