Let the terminal voltages at the two ends of the line section shown in Figure 8.24 be given by

The line impedances are given by:
\[
Z_{\mathrm{aa}}=j 60 \Omega \quad Z_{\mathrm{ab}}=j 20 \Omega \quad Z_{\mathrm{nn}}=j 80 \Omega \quad Z_{\mathrm{an}}=0 \]

(a) Compute the line currents using symmetrical components. (Hint: See Problem 8.27.)

(b) Compute the line currents without using symmetrical components.
