As we will learn in Chapter 8, to maximize the transfer of power from an input circuit to a load ZL, it is necessary to choose ZL such that it is equal to the complex conjugate of the impedance of the input circuit. For the circuit in Fig. P7.50, such a condition translates into requiring ZL = Zth*. Determine ZL such that it satisfies this condition.
