如何转换 电功率 中的 瓦特(W) to energy 中的 kilojoules (kJ).
You can calculate kilojoules from watts and seconds, but you can't convert watts to kilojoules s中的ce watt and kilojoule units represent different quantities.
能量 E 中的 kilojoules (kJ) is equal to the power P 中的 瓦特(W), times the time period t 中的 seconds (s):
E(kJ) = P(W) × t(s) / 1000
因此
千焦 = 瓦特 × 秒 / 1000
或
kJ = W × s / 1000
What is the energy consumption of an electrical circuit that has power consumption of 300 watts f或 time duration of 3 seconds
E(kJ) = 300W × 3s / 1000 = 0.9kJ
