#### Solution Preview

I have attached two files; one for impedance and other for admittance.

NOTE: For impedance calculations open circuit (current =0) concept is used, and for admittance calculations closed/short circuit (potential difference = 0) is used.

For impedance matrix, I have done ...

#### Solution Summary

For impedance calculations open circuit (current =0) concept is used, and for admittance calculations closed/short circuit (potential difference = 0) is used.
