I need to settle this debate once and for all. I have friends who say that a "thicker size braided wire" will carry more volts. The others say the same size "solid wire" will carry more voltage but harder to manage. I believe that the "solid wire" (same size) will carry more because there is less resistance than a stranded wire because electrons travel the path of least resistance. Can some one tell us who is right and why?

Many thanks
