The circuit in Figure P3–21 seems to require two supermeshes since both current sources appear in two meshes.

However, sometimes rearranging the circuit diagram will eliminate the need for a supermesh.

(a) Show that supermeshes can be avoided in Figure P3–21 by rearranging the connection of resistor R6.

(b) Formulate mesh-current equations for the modified circuit as redrawn in (a).

(c) Solve for vx when R1 ¼ R2 ¼ R3 ¼ R4 ¼ 4 kV, R5 ¼ R6 ¼

2 kV, iS1 ¼ 80 mA, and iS2 ¼ 40 mA.AppendixLO1
