EEK! #2 - DC vs The Magic of AC

In episode 2 of the EEK! series, we cover the basic difference between direct current (DC) and alternating current (AC). Why is your home powered by AC, and not DC?

Simply put, AC allows the use of transformers to step up the voltage, step down the current, and therefore bypass the little problem of too much current flowing over a thin wire.

DC cannot be easily converted in this way for efficient power transmission over long distances. There's more to say about AC, so look for a 3-phase video soon!
