Resonance Frequency of Circuit Involving Multiple Inductors

  1. Sep 28, 2012 #1
    I have two inductors and a capacitor in series, in the order of inductor, capacitor, inductor. I'm not sure if the equation L1+L2+k*√(L1*L2) will work in this case or not, given the inductors are separated (or offset) electrically from each other by a capacitor. So I guess my question is, can the formula for calculating effective inductance be used in this situation, or will I need a different formula?

    If there is no coupling between the inductors, then inductors in series simply add. (You treat the problem as impedances in series.)
