The circuit in given Figure 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 given Figure by rearranging the connection of resistor R6.
(b) Formulate mesh-current equations for the modified circuit as redrawn in part (a).
(c) Solve for vx when R1 = R2 = R3 = R4 =1kΩ, R5 = R6 = 10 kΩ, iS1 = 100 mA, and iS2 = 50 mA.
