    Hello everyone,

    I have attached the 3 questions I am wrestling with.

    For 10 I used the equation: f_{0}=\frac{1}{2\pi\sqrt{LC}} to obtain f_{0}=50.3kHz

    For 11 I used the equation: R_{D}=\frac{L}{r_{L}C}, with r_{L}=100\Omega to obtain R_{D}=100k\Omega

    For 12 I treated it as if it was a voltage divider so: V_{out}=1\times\frac{100k\Omega}{100k\Omega + 10k\Omega}=0.91V

    I feel as if this is incorrect. Can anyone just give this a quick check over as I am relatively new to AC circuits.

    Those answers look correct given a small tolerance because of numerical truncation to the given number of digits.
