D2 might be forward if (V_X) is higher than (V_Y). The resistor from D2 cathode to -5V means current can flow from X through D2, then through resistor to -5V. So D2 could also be forward. This becomes a three-diode simultaneous solution.

From D1: (V_X = 5 - 0.7 = 4.3V). From D3: (V_o = V_X - 0.7 = 4.3 - 0.7 = 3.6V). diode circuit analysis problems and solutions pdf

The full solution (3 pages) is provided in the PDF, showing how to use KCL at node X and node (V_o) to solve for all variables. D2 might be forward if (V_X) is higher than (V_Y)

Single-assumption guesses often fail in multi-diode circuits. You must solve simultaneous equations or use the iterative method described in Chapter 4 of the PDF. Common Mistakes Students Make (and How the PDF Helps) | Mistake | Correction in PDF | |---------|-------------------| | Forgetting to check reverse bias condition (voltage < 0) | Each solution includes a “Verification Box” | | Using 0.7V drop for Zener in forward bias | Clear distinction: Zener in breakdown = (V_Z), forward = 0.7V | | Ignoring the load effect on Zener current | Worked example with variable (R_L) | | Assuming ideal model when specific drop is given | Model selection flowchart in first chapter | Conclusion: From Confusion to Confidence Mastering diode circuit analysis is not about memorizing solutions—it is about learning a robust methodology . The “guess, solve, verify” loop, combined with an understanding of the three diode models, will let you tackle any diode problem, from simple rectifiers to complex clipping circuits. This becomes a three-diode simultaneous solution
