Power in Science
In science, power is the rate at which work is done or the rate at which energy is transferred or converted. It is a measure of how quickly something can be done. The unit of power is the watt (W), named after James Watt, the inventor of the steam engine.
How to Calculate Power
The formula to calculate power is:
Power (P) = Work (W) / Time (t)
or
Power (P) = Energy (E) / Time (t)
