Calculating Load Voltage and Current Values

                                    In half wave rectifier the load voltage may be found as

                                                                        V_L(pk) = V₂(pk) - V_F

                         V₂(pk) is the secondary voltage  of the transformer, determined as

                                                                         V₂(pk) = (N₂/N₁) V₁

                        Here

                                     N₂/N₁ = (it is the turn ratio of transformer secondary turns to primary turn)

                                    V₁(pk) = (It is the  peak transformer primary voltage)

Above equation suppose that the transformer is given as a peak value.

More frequently than not, source voltages are given as rms values. While this is the case, the source voltage is transformed into peak value like follows:

                                                V_pk  = V_rms/0.707
