1) Calculate the open circuit voltage VOC (ZL removed) (magnitude and phase angle)
2) Calculate the Thevenin Equivalent impedance ZTH for this circuit (magnitude and phase angle)
3) Create the Thevenin Equivalent circuit .
4) Calculate the load impedance ZL, that would dissipate the maximum power
5) Calculate IL and PL for this load for both the original circuit and the Thevenin Equivalent circuit
6) Use the same value load resistance, but remove the reactive component from load ZL1. this will be ZL2.
