Impedance for RLC circuits

  1. Apr 20, 2013 #1
    Hey. Say you have an RLC circuit with an AC supply. Then I=ei(ωt-α). My question is: will α always exist, ie will the current always be phase-shifted compared to the voltage, as long as the impedance has an imaginary component or if the circuit is not at resonance? Does Z = |Z|*e, where α = atan[im(Z)/re(Z)] ?
