    Can someone link me/explain to me the proof of this theorem? I can't seem to find it online. Thanks!!

    This is just part of the definition of a linear circuit: any circuit for which superposoption does NOT apply is nonlinear

    So how does one prove that the superposition theorem applies in a circuit containing only resistors, capacitors, inductors, and independent/dependent voltage/current sources?

    Perhaps start by demonstrating superposition for the individual components based on their transfer functions?

    [tex] I_{total} = C\frac{d(v1+v2)}{dt} = C\frac{dv1}{dt} + C\frac{dv2}{dt} [/tex]
