So the AC flow seeks out the lowest reactance towards the edges and in the case of the highest frequencies, like RF, the flow travels mainly along the skin. A DEEPER LOOK The way the physics works out ...

In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

There are two main types of electrical current that flow through your home: Alternating and direct. The vast majority of devices around you are powered by alternating current. By allowing ...
