## Main Question or Discussion Point

This is probably a dumb question, but I only need to know for a program I would like to write.

Basically, on average (I realize there are a lot of factors involved, but a rough estimate is all I need), how much energy dissipates over a specific length of a conductor (power lines, whatever they are made of)? (I don't know what an appropriate length would be, as I have no idea at all how far AC can travel. I have a vague idea of DC, but that is only because I am into networking.)

Also, since W=V*I, and I'm assuming that I shouldn't decrease, then V is what decreases?

Thank you.
