How to 转换 energy in kilojoules (kJ) to 电气 power in kilowatts (kW).
You can 计算 kilowatts from kilojoules and seconds, but you can't 转换 kilojoules to kilowatts, since kilojoule and kilowatt units represent different quantities.
The power P in kilowatts (kW) is equal to the energy E in kilojoules (kJ), divided by the 时间 period t in seconds (s):
P(kW) = E(kJ) / t(s)
So
kilowatt = kilojoule / second
or
kW = kJ / s
求 the power consumption of an electrical circuit that has energy consumption of 9 kilojoules for 时间 duration of 3 seconds
P(kW) = 9kJ / 3s = 3kW
