A fan and a hair dryer both move air. How do the watts used by each compare? Explain why there is such a difference.

One might think the hair dryer and ceiling fan have comparable electricity usage, since both items are small and the hair dryer is only used for short periods while fans are used for long periods of time. So the hair dryer can use a lot of energy at once while a fan needs to use the energy slowly. I hope that this exsplanation helps you.
