Q:      Find out the peak load voltage for the circuit shown in the diagram.

SOLUTION:

                        Primary, the ac input to the transformer is changed to a peak value, like follows

                                                V₁(pk) =    V₁rms/0.707

                                                            = 120/0.707= 169.7V_pk

                        Now, in the secondary circuit the voltage values are determined as

                                                 V₂(pk) = N₂/N₁(V_1pk)

                                                             = 1/5(169.7)

                                                  V₂(pk )= 33.94V_pk

                        As well as

                                                     V_Lpk = V₂(pk) - V_F

                                    Diode is a silicon diode

                                                           = 33.94 - 0.7

                                                  V_Lpk = 33.24V_pk
