PART B

6.Derive the relationship among submatrices of A,B,&Q.

7.Draw the graph of the given network and select a tree with branches having resistances 3ohm and 4ohm.

Draw the cutest matrix.Using topological form of KCL eqution find various branch voltages and currents.

The branch numbers are marked with integers in the figure while node numbers are encircled .

7. Derive the expression for Z parameters in terms of Y parameters.

9. Derive the condition for reciprocity &symmetry in ABCD parameter representation.
