It is well known that in order to solve diode circuits we must assume state of diodes, replace diodes with appropriate model (0.7V voltage drop) and solve circuit. Then we check result and if it agrees with initial assumption, we successfully solved our circuit.(adsbygoogle = window.adsbygoogle || []).push({});

If we mark number of diodes in circuit with n, there will be 2^n possible combinations of diode states. What to do in situation with 5 diodes, for example? You will agree that it will be quite impossible to check all combinations.

I was trying to find easiest way to solve multiple diodes circuits so I came up with this idea: I assume that all diodes in circuit are conducting so I replace all of them with 0.7V voltage drop and solve that circuit. Then I form another circuit which consist of 0.7V voltage drops instead of diodes for which I proved that conduct in previous step and open circuit for diodes I proved that doesn't conduct in previous step. Then I solve that circuit. Does my idea make sense? :)
