How to 변환 energy in joules (J) to 전기 power in watts (W).
You can 계산 watts from joules and seconds, but you can't 변환 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 시간 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 시간 duration of 3 seconds
P(W) = 90J / 3s = 30W
