The graph of this network is shown in Fig. 17.7-13(a). The dual graph is shown in
Fig. 17.7-13(b). Now, the dual network may be constructed by taking up similarly labelled
pairs of branches, one by one. For instance, consider the branches labelled 4 in both
networks. It is a 25 Ω resistance in the network in Fig. 17.7-13(a). Therefore, it has to be a
25 S conductance in the network in Fig. 17.7-13(b). Hence, 0.04 Ωis connected between
the second node and the reference node in the network in Fig. 17.7-13 (b).
Consider the branches labelled 5 in the two networks. It is a 0.25 H inductance in the
network in Fig. 17.7-13(a). Therefore, it has to be an ...
