In the balanced three-phase system in Figure P16-42 the line and load impedances are (Z_{mathrm{W}}=2+j 12 Omega

Question:

In the balanced three-phase system in Figure P16-42 the line and load impedances are $Z_{\mathrm{W}}=2+j 12 \Omega /$ phase and $Z_{\mathrm{Y}}=$ $16+j 10 \Omega /$ phase. The line current is $I_{\mathrm{L}}=15 \mathrm{~A}(\mathrm{rms})$. Find $V_{\mathrm{L}}$ at the source and the complex power produced by the source.
