Hey guys.
I'm a little bit lost for this question.
I need to fined the Thevenin and Norton equivalent cct's for the following cct. Given w = 10 rad/s
As you can see, it has a dependent source and two A.C independent sources.
From what I understand, I need to fined the open cct voltage (Vth) and short cct current (iN) across ab.
When I have the Vth and iN, Rth = RN = Vth/iN
right?
I'm having a little difficulty analysing this cct.
Should I be using nodal analysis to fined Vth?
and Mesh analysis to fined iN?
is this the best/easiest method?
Sorry if my question sounds silly... I haven't covered this in my lectures yet
this is what I have so far for iN
I1 = 2<-90
Vo = 10(I1 - I2)
loops
10(I1-I2) = 0
-j2(I2) + 25j(I2 - I3) = 12<0
25j(I3 - I2) - 2vo = 0
2vo = 0
10I1 - 10I2 = 0
(10 + j23)I2 + (25j)I3 = 12<0
-20I1 - (20 + j25)I2 + (j25)I3 = 0
20I1 - 20I2 = 0
thanks guys
