Solution In these circuits it might not be obvious at first sight whether none, one, or both diodes are conducting. In such a case, we make a plausible assumption, proceed with the analysis, and then check whether we end up with a consistent solution. For the circuit in Fig. 4.6(a), we shall assume that both diodes are conducting. It follows that V, = (0 and V=0. The current through D, can now be determined from
