Not sure I understand what you are saying. Unless the wrong terms are being used, but transformers "hate" DC. Plus also, think of voltage like water pressure: i.e. the higher the pressure the further the water travels. Also consider the Litz effect; higher frequencies tend to travel along the outer surface of the conductor(s), hence, multi strand cable etc. -- "Religion is excellent stuff for keeping common people quiet." -- Napoleon Bonaparte -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
