Comment convertir puissance électrique en kilowatts (kW) to energy en kilojoules (kJ).
You can calculate kilojoules from kilowatts and seconds, but you can't convert kilowatts to kilojoules sence kilowatt and kilojoule units represent different quantities.
L'énergie E en kilojoules (kJ) is equal to the power P en kilowatts (kW), times the time period t en seconds (s):
E(kJ) = P(kW) × t(s)
Donc
kilojoules = kilowatts × secondes
ou
kJ = kW×s
What is the energy consumption of an electrical circuit that has power consumption of 3 kilowatts fou time duration of 3 seconds
E(kJ) = 3kW × 3s = 9kJ
