The circuit in Figure P2−22 is organized around the three signal lines A, B, and C.
(a) Identify the nodes and at least five loops in the circuit.
(b) Write KCL connection equations for the circuit.
(c) If i1 = −30 mA, i2 = −18 mA, and i3 = 75 mA, find i4, i5, and i6.
(d) Show that the circuit in Figure P2−22 is identical to that in Figure P2−19.
