Question:

In Figure P16-20, the voltage across the two loads is $\mid V_{\mathrm{L}}$ I $=4.8 \mathrm{kV}$ (rms). The load $Z_{1}$ draws an average power of $15 \mathrm{~kW}$ at a lagging power factor of 0.8 . The load $Z_{2}$ draws an apparent power of $12 \mathrm{kVA}$ at a lagging power factor of 0.85 . The line has an impedance of $Z_{\mathrm{W}}=9+j 50 \Omega /$ wire. Find the apparent power produced by the source and the rms value of the source voltage.
