1.	A two-port network shown below is excited by external dc sources. The voltage and current are measured with voltmeters V1, V2 and ammeters A1, A2 (all assumed to be ideal) as indicated. under following switch conditions, the readings obtained are:(i) S1−open,S2−closed A1=0 A , V1=4.5 V , V2=1.5 V , A2=1 A(ii) S1−closed,S2−open A1=4 A, V1=6 V , V2=6V , A2=0 AThe Z-parameter matrix for this network is
Answer» A two-port network shown below is excited by external dc sources. The voltage and current are measured with voltmeters $V_{1}$ , $V_{2}$ and ammeters $A_{1}$ , $A_{2}$ (all assumed to be ideal) as indicated. under following switch conditions, the readings obtained are: $(i) S_{1} - o p e n, S_{2} - c l o s e d A_{1} = 0 A, V_{1} = 4.5 V, V_{2} = 1.5 V, A_{2} = 1 A$ $(i i) S_{1} - c l o s e d, S_{2} - o p e n A_{1} = 4 A, V_{1} = 6 V, V_{2} = 6 V, A_{2} = 0 A$ The Z-parameter matrix for this network is
