In Figure 1, the 3-phase source has a line-to-line voltage of 440 volts. The details of the impedances are the following: - \( Z_1 = 36 - j15 \, \Omega \)- \( Z_2 = 40 + j30 \, \Omega \)- \( Z_3 = 45 + j60 \, \Omega \)- \( Z_4 = 75 + j0 \, \Omega \)- \( Z_5 = 50 + j50 \, \Omega \)- \( Z_6 = 20 + j48 \, \Omega \)Determine the following:(a) Line currents: \( I_{a1}, I_{b1}, \) and \( I_{c1} \);(b) Line currents: \( I_{a2}, I_{b2}, \) and \( I_{c2} \);(c) Line currents: \( I_{aT}, I_{bT}, \) and \( I_{cT} \);(d) \( P_T, Q_T, S_T, \) and \( pf_T \) for the system;(e) \( W_1 \) and \( W_2 \) readings for 2-wattmeter method at lines \( a \) and \( b \).**Diagram Explanation:**- The figure represents a balanced 3-phase \( ab-bc-ca \) source. - The diagram shows three sets of line currents \( I_{aT}, I_{bT}, \) and \( I_{cT} \) flowing from the source to the loads. - There are branches for each phase labeled with currents \( I_{a1}, I_{b1}, \) and \( I_{c1} \) for the first part and \( I_{a2}, I_{b2}, \) and \( I_{c2} \) for the second part.- Impedances \( Z_1, Z_2, Z_3 \) form a delta configuration, while \( Z_4, Z_5, \) and \( Z_6 \) seem to be connected in a different configuration at the load side.- The current directions are indicated by arrows on the lines. This setup is typically analyzed using methods for solving balanced 3-phase circuits to find the line currents, powers, and measurements using a two
