如何转换 电功率 中的 千瓦(kW) to energy 中的 kilojoules (kJ).
You can calculate kilojoules from kilowatts and seconds, but you can't convert kilowatts to kilojoules s中的ce kilowatt and kilojoule units represent different quantities.
能量 E 中的 kilojoules (kJ) is equal to the power P 中的 千瓦(kW), times the time period t 中的 seconds (s):
E(kJ) = P(kW) × t(s)
因此
千焦 = 千瓦 × 秒
或
kJ = kW×s
What is the energy consumption of an electrical circuit that has power consumption of 3 kilowatts f或 time duration of 3 seconds
E(kJ) = 3kW × 3s = 9kJ
