Homework Help: Quick question about RLC circuit energy and quality factor

  1. Sep 11, 2009 #1
    1. The problem statement, all variables and given/known data
    My book defines the equation for energy of an RLC circuit to be E = 1/2 L I^2 + 1/2 Q^2/C
    In series the Quality factor is (L/C)^1/2/R

    My question is will these equations hold for an RLC circuit that is parallel. I.E. the Resistor is in parallel with the Inductor which is in parallel with the capacitor.

    It is the reciprocal of the series oneƍ: R*(C/L)^1/2.
