om..

I was talking to an electrician doing some work in my building and
started asking some questions about AC. My electrical knowledge is
quite limited, but in the course of the conversation, I said something
about the the flow of current reversing direction twice every 60th of
a second. He said "No, the ACTUAL current always flows in one
direction from the hot to the neutral and it's the AMOUNT of current
flowing that alternates." Isn't that the definition of modulated DC,
not AC? I couldn't make any sense of his explanation of what he meant
by "actual current", but he insisted that current flows in ONE
DIRECTION ONLY. I really don't get what he's talking about - but he's
the professional. Can someone fill me in?



** He is using "electrician's logic".

The "hot" wire is the one with electricity in it because it can give him a
shock while the neutral has no electricity in it because it does not.
Therefore the electricity flows from the hot to the cold - just like heat
does - in only one direction.
