Kirchhoff's circuit analysis for the curious

Kirchhoff is often mentioned on this forum. These two videos explain Kirchhoff. This may be interesting to some that want to understand more about their 12V DC circuits. It is very advanced for the beginner and uses some math.

    Spice just shoot nodal analysis out of the water. It's like taking a pea shooter to a gun fight. I recall my nodal analysis to arrive at battery bank current sharing and then you come along with fancy spice graphs.

    But, there's something to be said about the old school method. Once the machines take over, you can't trust the computer anymore. ;-)


    You need to understand the theory so you can do a sanity check on the Spice results. I have seen new engineers do an analysis with an input modeling error and get bogus results they took as valid results.

  • very good tutorials. Takes me back to my freshman basic circuit theory classes. His enthusiasim reminds me of some of my best professors.

    Now a good video on Thevenin and Norton equivalent circuits would be another good one for reference.
