Since the 3-V source has a polarity that results in forward bias of the diode, we assume that the operating point is on line segment A of Figure 10.19. Consequently, the equivalent circuit for the diode is the one for segment A. Using this equivalent circuit, we have the circuit of Figure 10.20(b). Solving, we find that iD = 80 mA.
