How to convert energy in kilojoules (kJ) to electric power in kilowatts (kW).
You can calculate kilowatts from kilojoules and seconds, but you can't convert kilojoules to kilowatts, since kilojoule and kilowatt units represent different quantities.
The power P in kilowatts (kW) is equal to the energy E in kilojoules (kJ), divided by the time period t in seconds (s):
P(kW) = E(kJ) / t(s)
So
kilowatt = kilojoule / second
or
kW = kJ / s
The formula for converting energy in kilojoules to power in kilowatts is given by:
P(kW) = E(kJ) / t(s)
where
P is the power in kilowatts, E is the energy in kilojoules, and t is the time period in seconds.To use this formula, simply substitute the values for E and t into the equation and solve for P. In the example you provided, the energy consumption was 9 kilojoules and the time duration was 3 seconds, so the power consumption is calculated as follows:
P(kW) = 9 kJ / 3 s = 3 kW
Therefore, the power consumption of the electrical circuit in this example is 3 kilowatts.
