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

Homework Equations

The Attempt at a Solution

Thevenin equivalent

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

Homework Statement

My problem is Norton equivalent.Can it be represented like this:

and then I_N=V_TH/Z_TH,once I find I_N can easily calculate I_L=I_N(Z_TH/Z_TH+R_L)

Those values look fine.

Then I converted them in polar forms
Thefore I calculated the current through the load resistor I=V_TH/Z_TH+R_L
I=0.489<-18.401

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

Yes, that's correct.
