Assuming the diodes to be ideal, find the values of I and V in the circuits of Fig. 4.6. + 10 V + 10 V 10 kM 5 k. V B 5 kM 10 kΩ - 10 V - 10 V (a) (b) Figure 4.6 Circuits for Example 4.2. 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

Example 4.2 Assuming the diodes to be ideal, find the values of I and V in the circuits of Fig. 4.6. + 10 V + 10 V 10 kN 5 kN D, ZD2 V B 5 kN 10 kn - 10 V - 10 V (a) (b) Figure 4.6 Circuits for Example 4.2. 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
