3.7 Exercise A single phase power system consists of 480V-60 Hz generator supplying a load $Z_{load} = (4 + j3)\Omega$ through a transmission line of impedance $Z_{line} = (0.18 + j0.24)\Omega$. Answer the following questions about this system. a- If the power system is exactly as described above (figure 3.9), what will the voltage at the load be? What will the transmission line losses be? b- Suppose a 1:10 step-up transformer is placed at the generator end of the transmission line and a 10:1 step-down transformer is placed at the load end of the line (as shown in figure 3.10). What will the load voltage be now? What will the transmission line losses be now?

A power transmission system is modeled as shown in Fig. $9.82 .$ Given the source voltage $\mathbf{V}_{s}=115 / 0^{\circ} \mathrm{V},$ source impedance $\mathbf{Z}_{s}=1+j 0.5 \Omega,$ line impedance $\mathbf{Z}_{\ell}=0.4+j 0.3 \Omega,$ and load impedance $\mathbf{Z}_{L}=23.2+j 18.9 \Omega,$ find the load current $\mathbf{I}_{L}$.
