SUMMARY

The discussion focuses on calculating the input and transfer impedances in a three-loop electrical circuit using mesh analysis. The circuit parameters include resistances R_1=2, R_2=5, R_3=10, a capacitor C_1 with an impedance of -j4, and an inductor L_1 with an impedance of j5, with a voltage source V=50e^{j0}. The user seeks assistance in establishing the impedance matrix (Z matrix), which is a 3x3 matrix where the diagonal elements represent driving point impedances and the off-diagonal elements represent transfer impedances. The user correctly identifies that Z_{input1} is calculated as Z_{input1}=\frac{50e^{j0}}{I_1} and requires further clarification on Z_{transfer12} and Z_{transfer13}.

Homework Statement


Hello,
I have encountered some sort of notation that I am not familiar with in regards to impedance. As an example, I have depicted a network here
hehe.jpg

The top loop is considered loop 1, the bottom-left loop is considered loop 2, while the bottom-right loop is loop 3.
R_2=5, R_3=10, R_1 2, C_1=C-2=-j4, L_1=j5, V=50e^{j0}
Using mesh currents I_1, I_2, I_3 in clock-wise direction, find Z_{input1}, Z_{transfer12}, Z_{transfer13}
I cannot seem to find anything in my notes regarding this... Any help is greatly appreciated. :)

I believe
Z_{input1}=\frac{50e^{j0}}{I_1}
However, the "transfer12" and "transfer13" impedances are not making any sense to me.
 
They want you to set up the impedance matrix (Z matrix) for the circuit. Since there are 3 loops, the matrix will be a 3x3 matrix.

The elements on the main diagonal, the Z(n,n) with n = 1 to 3, are the driving point impedances. The off diagonal elements are the transfer impedances.

Zinput1 will be the 1,1 element of the Z matrix. Ztransfer12 will be the 1,2 element, etc.
