(a) Formulate node-voltage equations for the circuit in Figure P3–9.

(b) UseMATLAB to find symbolic expressions for the node voltages in terms of the parameters in the circuit.

(c) Find numeric values for vA, vB, and vC when R1 ¼ 1.5 kV, R2 ¼ 2.2 kV, R3 ¼ 3.3 kV, R4 ¼ 4.7 kV, and iS1 ¼ iS2 ¼ 2 mA.

(d) Use OrCAD to verify your solution to part

(c) is correct.AppendixLO1
