What is Power?

In physics and engineering, Power is the rate at which work is performed or energy is transferred. While energy represents the total capacity to do work, power measures how quickly that capacity is used. Two light bulbs might consume the same amount of energy over different periods, but the one that consumes it faster has a higher power rating.

Common Power Units

W

Watt (W)

The SI unit of power, defined as one joule per second. Used for almost all electrical appliances.

hp

Horsepower (hp)

A unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors.
