Q: Find output voltage utilizing silicon diode along V_T = 0.7V

SOLUTION:

Now for the short circuit state the network takes the appearance of the diagram. and V₀ may be find out by KVL  equation in the output section

                                                            +5 - 0.7 - V₀ = 0

                                                                           V₀ = 4.3V

                        For the input section KVL equation shall result in

                                                            -20 +V_c + 0.7 - 5 =0

                                                                                  V_c = 25 - 0.7 =24.3V

                        For the time period t2 to t3 the network shall now appear as in diagram. By  applying KVL equatin

                                                                        10 + 24.3 - V₀ = 0

                                                                        V₀ = 34.3V
