Draw the dual of the network shown in Figure.
Solution:
(a) Place a node inside each mesh.
(b) Place a node outside the mesh which will correspond to the datum node.
(c) Connect internal nodes through a dashed line. The element which is dual of the common branch (here capacitance) will form the branch connecting the corresponding independent node in the dual network.
(d) Connect all internal nodes to the external node by dashed lines crossing all the branches. The dual of these branches will form the branches connecting the independent node and datum.
