변환 방법 전력 의 와트(W) to energy 의 kilojoules (kJ).
You can calculate kilojoules from watts and seconds, but you can't convert watts to kilojoules s의ce watt and kilojoule units represent different quantities.
에너지 E 의 kilojoules (kJ) is equal to the power P 의 와트(W), times the time period t 의 seconds (s):
E(kJ) = P(W) × t(s) / 1000
따라서
킬로줄 = 와트 × 초 / 1000
또는
kJ = W × s / 1000
What is the energy consumption of an electrical circuit that has power consumption of 300 watts f또는 time duration of 3 seconds
E(kJ) = 300W × 3s / 1000 = 0.9kJ
