    Looks to be right on target to me, basic EM field theory of electricity.

    Hi,
    Can you tell me why or where it is wrong? I can't recognize what is wrong? I intented to read it to help me understand basic things but I am confused.

    For the purposes of learning basic circuit analysis methods, the details of the ultimate physics beneath the phenomena are not as important as having a standard working model that is consistent, easy to apply, and yields equations and solutions that accord with measurements of real circuits. The potential \ current flow model, along with electrostatics and magnetism as present by your school texts should be more than adequate, and will accord exactly with what your expected to know for examination purposes.

    When you move on to more advanced electromagnetic theory and study how energy can be transported by waves in fields and so on, then more of the the particulars of the underlying model will become important.

    My simple dismissing of the paper as "crap" was hasty and perhaps unfair. I should have taken the time to formulate a more cogent response. Sorry about that!

    Every few days we have some poor confused person trying to shake off the first impressions of this 'working model' that makes it easy for simple testing.

    The basic understanding of EM fields actually helps students with understanding circuit theory and the lack of that understanding leaves them with a first impressions mental block to seeing how beautiful the reality of electricity and circuits is.
