Watt vs watt-hour.

210 viewsEngineeringOther

Would I be correct in saying 1 watt means the device will need 1 watt every second to function, whereas, 1 watt-hour means after 1 hour of running, the device would have had 1 watt flow through it every second? Meaning it transferred 60 watts in that hour to a different form of energy?

Watt is a unit of power, meaning something that requires 1 watt of power requires 1 Joule per second of energy.

So a watt hour is the amount of energy a device that draws 1 watt will use in an hour. Since a watt is 1 joule per second, a watt hour is equivalent to 3600 Joules.

So the power draw in watts is like mesureing speed whilst the energy (measured in watt hours) is like mesureing distance.
