    Use Thevenin’s and Norton’s theorems to find the current in RL for the circuit

    2. Relevant equations



    3. The attempt at a solution
    Thevenin equivalent

    I have calculated VTH and ZTH
    VTH=33.793-j5.517
    ZTH=19.068+j11.172
    Then I converted them in polar forms
    Thefore I calculated the current through the load resistor I=VTH/ZTH+RL
    I=0.489<-18.401

    1. The problem statement, all variables and given/known data
    My problem is Norton equivalent.Can it be represented like this:

    and then IN=VTH/ZTH,once I find IN can easily calculate IL=IN(ZTH/ZTH+RL)

    Those values look fine.

    The current magnitude looks good. Maybe a typo in the second decimal place of the angle?

    Yes, that's correct.
