Q:     Calculate the values of V_L(pk)&  V_ave for the circuit indicated in the diagram.

SOLUTION:

            The transformer is rated at 30V_ac. So, the value of V₂(pk) is determined as

                                       V₂(pk) = 30V_ac/0.707= 42.2Vpk

                                    The peak load voltage may now determined as

                                                              V_l = V₂/2 - 0.7

                                                            =21.2 - 0.7 //put the value from above

                                                             = 20.5V_pk

                        At last the dc load voltage is determined as

                                                      V_ave = 2V_L/ Π

                                                                           =41V_pk/ Π=13.05V_dc
