(b) Figure 5 shows a three-phase supply of 240 V in A-configuration connected to a balanced load comprising three impedances of (10 + j20) N in Y-configuration. Given that the voltages of Vab, Vbc and Vca are at 15°, -105°, and 135°, respectively. [Rajah 5 menunjukkan satu sumber tiga-fasa 240 V dalam konfigurasi-A bersambung kepada beban terimbang yang terdiri daripada tiga galangan (10 + j20) Q dalam konfigurasi-Y. Diberikan voltan Vab, Vbe dan Vea masing-masing adalah pada 15°, -105° dan 135°.] I, Figure 5 [Rajah 5] (i) Sketch a phasor representation of Vab, Vbc, and Vca in the same graph. [Lakarkan perwakilan pemfasa Vab, Vše dan Vea di dalam graph yang sama.] (ii) Calculate the values of Ia, Ib, and Ie and state your answers in polar form. [Kirakan nilai-nilai Ia, Is dan Ie dan nyatakan jawapan-jawapan anda dalam bentuk polar'] (iii) Determine the total real power consumed by the load.
