    A few weeks I looked for these youtubes so as to insert in another thread.
    I had forgotten the lecture names so I never found it then... but I found it a few minutes ago.

    Kirchhoff's rule is for the birds, Faraday's law is incorrectly taught in texts and colleges

    Lec 16 | MIT 8.02 Electricity and Magnetism, Spring 2002

    The handling of non-conservative fields versus conservative fields.
    The implications into Kirchhoff's laws a special case of Faraday's laws.
    Faraday's laws always hold and Kirchhoff's law is for the birds.

    I like the way Walter Lewin makes dotted lines. His hand doesn't even move

    Yup; it's precisely the point made in the other thread about potentials and voltage dividers. Kirchhoff's "laws" (note the double-h in Kirchhoff; it's one of the most misspelled names in all of science and engineering) aren't laws at all. And contrary to Mayflow's charge that knowing this is an example of "over"education, a conscious violation of the underpinnings of Kirchhoff's voltage law is what enables the cyclotron to produce such high energies.

    And finally, while we're in a nitpicking phase, it's "Lewin," not "Lewen." He's a good guy; we should do him the honour of spelling his name correctly.

    I corrected myself viz the spelling issues.

    As for the "over education" falderal. There are categories of posters who name drop and concept drop some with intimate understanding of and experience with the issues, others with a higher than average knowledge, autodidact amateurish understanding that does not stand up to scrutiny nor three hour exams, others that just throw it in because they can.

    BTW, in my world travels I,Ve had to pick a few nits.
