Como converter potência elétrica em quilowatts (kW) to energy em kilojoules (kJ).
You can calculate kilojoules from kilowatts and seconds, but you can't convert kilowatts to kilojoules semce kilowatt and kilojoule units represent different quantities.
A energia E em kilojoules (kJ) is equal to the power P em quilowatts (kW), times the time period t em seconds (s):
E(kJ) = P(kW) × t(s)
Poutanto
quilojoules = quilowatts × segundos
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
