如何将焦耳 (J) 为单位的能量转换为 电功率 为单位的 瓦特 (W)。
You can calculate 瓦特 from joules and seconds, but you can't convert joules to watts, s为单位的ce joule and watt units represent different quantities.
功率 P 为单位的 瓦特 (W) is equal to the energy E 为单位的 joules (J), divided by the time period t 为单位的 seconds (s):
P(W) = E(J) / t(s)
所以
瓦特 = 焦耳 / 秒
或
W = J / s
What is the power consumption of an electrical circuit that has energy consumption of 90 joules f或 time duration of 3 seconds
P(W) = 90J / 3s = 30W
