Homework Help: Resistance, Inductance and Capacitor

  1. Jan 26, 2014 #1
    Can some check my answer, please? I only did number 1 because I have no idea how to do number 2.

    NOTE: Calculators are not allowed, so no need to give the exact value. For example, if the answer has √2, just leave it as √2, instead of writing it as 1.41.......

    Power source voltage e(t) = √2*20sin2t [V],
    current i(t) = 5sin(2t - ∏/4) [A].

    1. Find the values of resistance R, and inductance L.
    2. Let V be the phasor of voltage v(t). Find the capacitance value of the capacitor C that maximizes the magnitude of V.
