Power is measured in what unit?

Explanation:
Power is the rate at which energy is transferred or work is done. In the SI system, the unit of power is the watt, defined as one joule of energy transferred per second. So if something uses energy at a rate of one joule per second, its power is one watt. For example, a light bulb rated at 60 watts uses energy at 60 joules every second. This shows how power relates energy and time, unlike energy measured in joules, force in newtons, or distance in meters.
