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?
In: Engineering
A watt is a unit of power, a watt-hour (or a joule) is a measure of energy. Power measures how big of a rock you can push, energy measure how far (or long) you can push the rock. They can be the same form of energy or they can be different forms, they’re measuring differing things.
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.
