AI Thread Summary
The discussion focuses on using Thevenin’s and Norton’s theorems to determine the current in a load resistor (RL) in a given circuit. The user successfully calculated the Thevenin equivalent voltage (VTH) and impedance (ZTH), resulting in VTH=33.793-j5.517 and ZTH=19.068+j11.172. They then converted these values to polar form and calculated the current through the load resistor, yielding I=0.489<-18.401. A query regarding the Norton equivalent was raised, confirming that IN can be derived from VTH/ZTH, allowing for the subsequent calculation of load current (IL). The calculations and methodology presented are validated by other participants in the discussion.

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

TASK1_A.jpg


Homework Equations


The Attempt at a Solution


Thevenin equivalent
THEV.jpg


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

Homework Statement


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.

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

Yes, that's correct.
