The power P in watts (W) is equal to 1000 times the energy E in kilojoules (kJ) divided by the time period t in seconds (s):
P(W) = 1000 * E(kJ) / t(s)
Watts = 1000 * Kilojoules / Seconds
W = 1000 * kJ / s
Find the power consumption of an electrical circuit that has an energy consumption of 9 kilojoules for a time duration of 3 seconds.
P(W) = 1000 * 9kJ / 3s = 3000W
