Power Power is the rate at which work is done. \ [P = \dfrac {W} {t}\] The SI unit for power is the watt \ (W\), where 1 watt equals 1 joule/second \ ( (1 \, W = 1 \, J/s)\). Because work is energy transfer, power is also the rate at which energy is expended. A 60-W light bulb, for example, expends 60 J of energy per second.
