Hmm... Alternating Current is the AC right? With the other one the Direct Current, and since the direct Current only goes in one direction with the Alternating Current go back and forth.
So in essence it would make less wires or time? Or that an AC current can be increased or decreased in power? Sorry, just really not good at this, I need to get my T.L.E book.
Um... I'm in High School II year, or 8th grade equivalent in America. But I have many thirst for knowledge with learning stuff fast sometimes.
Also I talked to my mom when I was young.. about that my parents bought a lot in the Philippines next to the shore, and she said it belongs to me and my brother, and I promised(Me bing young at that time with love of building) that I would build a house there. So can carpentry work on going? Because Architecture is what I'm trying to learn as well.
One more thing, have you heard a house made from reinforced concrete, takes a very long time, but it resists a lot of damage, and contains heat saving energy. That's my house.
A text book would be a good idea, we would a frame of reference in which to study.
