What's the difference between watts and watt hours?

What's the difference between watts and watt hours?

Watt and watt hours are often interchanged, misused and can be just plain confusing. A watt (W) is a measurement of power which is the rate of electricity that is being generated or consumed. A watt hour (wh) is the same energy over a period of time. A light bulb rated at 20 watts, in 1 hour it will consume 20 wh of energy, and in 5 hours the same light bulb will consume 100 wh of energy. 1 watt hour (wh) = 1 watt of power supplied for 1 hour. Think of watts (w) as the speed you’re running and watt-hours (wh) as the distance you ran. Ok professor, need to go deeper? One joule per second is a measurement of the rate of power flowing. 1 watt is a unit of energy equal to the power of one watt operating for one hour or 3,600 joule's.
