Non-conservative circuits

  1. Sep 22, 2015 #1
    Why can't Kirchoff's Laws be applied to a non-conservative circuit?. I'll be looking forward to a good discussion.

    Hi Arvind, welcome to PF!

    What is a non conservative circuit? I have never heard the term.

    I guess that term is wrong. Suppose there is an inductor in a circuit, it is said the conceptually Faraday's laws are more superior that Kirchoff's laws. Why?

    Your question is why does a description of what happens with an all-resistor circuit fail when you use a non-all-resistor circuit? Same reason a law about gasses fails when you talk about solids, or a law about metals fails when talking about non-metals, and so on. A mathematical description of a certain system describes that system - not necessarily some other system.

    They are for 2 different things ... you cannot really compare them

    have you even googled the 2 to see the differences ?

    I wouldn't say specifically Faraday's law is superior. What you can say is that you can derive KCL and KVL from Maxwell's equations, but not the other way around. But you need all of Maxwell's equations, not just Faraday's law. And a better term is "more general" rather than "superior".
