Homework 8 Due: Monday, September 12 1 Consider the circuit of Figure 1. (a) Write two node equations in terms of the literal variables in Figure 1 and put them in matrix form. (b) Solve the node equations for the voltages V A and V B when I s 1 = 0 . 5 A, I s 2 = 1 A, g m 1 = 35 mS, g m 2 = 10 mS, G 1 = 2 mS, G 2 = 3 mS, and G 3 = 1 S. (c) Determine V 0 . (d) Determine the power delivered by each source. (Be careful of the sign.) Friday, September 9, 2011 Figure 1: Model circuits for Problem 1. 2 Consider the circuit of Figure 2. By choosing node C as the reference node, we eliminate a ﬂoating voltage source. Write an appropriate set of nodal equations, with node C as the reference node. Solve the nodal equations, specify the voltages

Let R 1 = 4 k Ω, R 2 = 6 k Ω, R 3 = 2 k Ω, R 4 = 3 k Ω, r m = 1 k Ω, and I s = 60 mA. Friday, September 9, 2011 Figure 2: Model circuit for Problem 2. 3 In the circuit of Figure 3, R 1 = 80 Ω, R 2 = 10Ω, and μ = 0 . 75. If V in = 10 V, ﬁnd I in , the power delivered by the independent and dependent voltage sources, and the equivalent resistance, R eq , seen by the independent source.
