    The circuit under is what I've got. Negate the Inductance on Inductors and capacity on Capacitors (I couldn't remove the labels). What matters is their inner resistance (X1,X2,X3). So, I've got this: Voltage between points A and B (Measured by the Voltmeter) is Uab=30V.Resistance equals R1=R3=X1=X2=2 Ohms, R2= 1 Ohm, X3 = 6 Ohms. Currents I1, I2, I3 is what I need. The circuit is connected to an AC source which is not given in the picture. Any help is appriciated, thanks.

    We cannot determine a value for you for any of that...
    You mentioned we should ignore the Inductance and Capacitance values and focus on their internal resistance... but this cannot be done.
    You need to:
    A) Provide us with the current value you want us to use for resistance for X1, X2, and X3.
    B) Provide us with the frequency of the AC source.

    The equivalent resistance of those components will depends entirely on the source frequency...

    Hmm, that's All I have on the info from the Excercise. All I know is their internal resistance. The frequency does affect it, but so does the Inductance and Capacity but they're irrelevant, (so I suppose I could swap the Conductors and Inductors with basic resistors?). The calculations are supposed to be done through complex numbers, and Kirchhoff's laws(contours).
