The power P in kilowatts (kW) is equal to the energy E in joules (J) divided by 1000 times the time period t in seconds (s):
P(kW) = E(J) / (1000 * t(s))
Kilowatts = Joules / (1000 * seconds)
kW = J / (1000 * s)
Find the power consumption of an electrical circuit that has an energy consumption of 90 joules for a time duration of 3 seconds.
P(kW) = 90J / (1000 * 3s) = 0.03kW
