줄 (J) 단위의 에너지를 전력 단위의 와트 (W)로 변환하는 방법.
You can calculate 와트 from joules and seconds, but you can't convert joules to watts, s단위의ce joule and watt units represent different quantities.
전력 P 단위의 와트 (W) is equal to the energy E 단위의 joules (J), divided by the time period t 단위의 seconds (s):
P(W) = E(J) / t(s)
따라서
와트 = 줄 / 초
또는
W = J / s
What is the power consumption of an electrical circuit that has energy consumption of 90 joules f또는 time duration of 3 seconds
P(W) = 90J / 3s = 30W
