Current Source and Figure

Conventions for Describing Networks 2-1. For the controlled (monitored) source shown in the figure, prepare a plot similar to that given in Fig. 2-8(b). v2 v1 = Vb (Vb v1 = Va (Va i2 Fig. 2-8 (b) Solution: Open your book & see the figure (P/46) It is voltage controlled current source. i2 +Ve axis v2 -Ve axis gv1 i2 gv1 + v2 current source - 2-2. Repeat Prob. 2-1 for the controlled source given in the accompanying figure. Solution: Open your book & see the figure (P/46) It is current controlled voltage source. v2 ri1 i2 2-3.

In (a) of the figure is shown a resistive network. In (b) and (c) are shown graphs with two of the four nodes identified. For these two graphs, assign resistors to the branches and identify the two remaining nodes such that the resulting networks are topologically identical to that shown in (a). Solution: Open your book & see the figure (P/48) b R2 R3 R1 a c R5 R4 d R4 d c R5 R1 R3 b R2 a 2-11. Three graphs are shown in figure. Classify each of the graphs as planar or nonplanar. Solution: Open your book & see the figure (P/48) All are planar. In that they may be drawn on a sheet of paper without crossing lines. 2-12. For the graph of figure, classify as planar or nonplanar, and determine the quantities specified in equations 2-13 & 2-14. Solution: Open your book & see the figure (P/48) Classification: Nonplanar Number of branches in tree = number of nodes – 1 = 5 – 1 = 4 Number of chords = branches – nodes + 1 = 10 – 5 + 1 = 10 – 4 = 6 Chord means ‘A straight line connecting two points on a curve’. 2-13. In (a) and (b) of the figure for Prob. 2-11 are shown two graphs, which may be equivalent. If they are equivalent, what must be the identification of nodes a, b, c, d in terms of nodes 1, 2, 3, 4 if a is identical
