(a) No load: ( I_Z = (15-9)/220 = 27.3mA ), ( V_o = 9V ). (b) Max load current occurs when ( I_Z = I_Zmin = 5mA ): ( I_L = I_Rs - I_Z = (15-9)/220 - 5mA = 27.3 - 5 = 22.3mA ). (c) Min ( R_L = V_Z / I_Lmax = 9V / 22.3mA = 403.6\Omega ). Check Zener power: ( P_Z = V_Z \times I_Zmax ), with ( I_Zmax = 27.3mA ) (no load) → ( P_Z = 9 \times 0.0273 = 0.246W < 1W ), safe. 7. Summary Table of Solution Methods | Circuit Type | Key Approach | |--------------|----------------| | Single diode | Assume state, solve linear circuit, verify | | Multiple diodes | Guess states, solve KVL/KCL, check consistency | | Rectifiers | Use constant-voltage drop, compute PIV | | Clippers | Identify reference voltages, add batteries | | Zener regulators | Ensure ( I_Zmin < I_Z < I_Zmax ) | 8. Conclusion Solving diode circuits requires checking the conduction state of each diode. The ideal and constant-voltage models offer practical accuracy for most engineering applications. The problems above illustrate the most common configurations. For further practice, the reader is encouraged to vary component values and add capacitors for filtering. References
