                                                               Zth  = [(8 + 6) is parallel to (j10)] + (– j14)

                                                                = [(14) // (j10)] + (– j14)

                                                                  = [  (14)( j10)  ] – j14
                                                                    (14 + j10)
                                                                = (4.73 – j7.378) Ω

                       Step 2


                       Calculate the value of Thevenin voltage, Vth by removing the 12Ω load from the circuit.
                       There are two methods to find the value of Thevenin voltage, Vth.

                       Method #1

                                Vth = Vj10Ω = i x (j10)


                          By using Current Divider Rule (CDR),


                                i    =    (6)   x 4A = (1.135 – j0.811) A
                                  (6+ 8 + j10)

                                Vth = Vj10Ω = i x (j10) = (1.135 – j0.811) x (j10) = (8.11 + j11.35) V
