    Parallel LCR resonant frequency derivation for larger resistances

    Ah ok, that is what I did, I wasn't aware there was another way to do it, I just omitted it from the working because it's the same for any question. The method is shown http://tutorial.math.lamar.edu/Classes/DE/ComplexRoots.aspx" for those wondering how I suddenly leapt to the frequency from...

    Parallel LCR resonant frequency derivation for larger resistances

    Thanks for replying so quickly, I'm glad you agree. Fedex: I'm not sure whether you mean your 3rd sentence to be connected to the 2nd or the 4th. Anyway, I have used complex numbers, which is why the arguments under the square root changed signs. As turin said, I'd assumed 1/LC > R2/4L2. Which...

    Parallel LCR resonant frequency derivation for larger resistances

    [SOLVED] Parallel LCR resonant frequency derivation for larger resistances There have been similar questions here before which I have seen, but I couldn't find an answer with the detail I require. Homework Statement I would like to derive an expression for the resonant frequency of a...
