                       Step 4


                       Calculate the current flowing through 12Ω resistor.


                                     (8.11 + j11.35 )
                          i12Ω   =                   = (0.155 + j0.747) Amps
                                  (4.73 − j7.378) + (12)


                       The current flowing through the 12Ω resistor = (0.155 + j0.747) Amps




                       Example 7


                       Determine the current that flows through (5 + j10) Ω using Thevenin’s theorem.

                       Step 1


                       Remove the impedance (5 + j10) Ω from the circuit and replace the voltage source with

                       a short circuit. Hence, calculate the value of Zth.
