3–20

(a) Formulate mesh-current equations for the circuit in Figure P3−20.

(b) Use MATLAB to find symbolic expressions for vx and ix in terms of the parameters in the circuit.

(c) Find numeric values for vx and ix when R1 =R2 =8:2 kΩ, R3 =2:2 kΩ,R4 =3:3 kΩ, iS =2:5 mA, vS1 = 15 V, and vS2 =5V.

(d) Find the power supplied by vS1.

(e) Use Multisim to verify your solutions to parts

(c) and (d)

are correct.
