How to 변환 전기 power in kilowatts (kW) to energy in kilojoules (kJ).
You can 계산 kilojoules from kilowatts and seconds, but you can't 변환 kilowatts to kilojoules since kilowatt and kilojoule units represent different quantities.
The energy E in kilojoules (kJ) is equal to the power P in kilowatts (kW), times the 시간 period t in seconds (s):
E(kJ) = P(kW) × t(s)
So
kilojoules = kilowatts × seconds
or
kJ = kW×s
What is the energy consumption of an electrical circuit that has power consumption of 3 kilowatts for 시간 duration of 3 seconds
E(kJ) = 3kW × 3s = 9kJ
