A three-phase line has an impedance of 1 + j2 Ω per phase. Theline feeds two balanced three-phase loads that are connected inparallel. The first load is Y-connected and has an impedance of20+j40 Ω per phase. The second load is ∆-connected and has animpedance of 30-j60 Ω per phase. The line-to-line voltage at theload end of the line is 415V. Taking the phase voltage Va asreference, determine: a) The total current per phase from thesource end .b) The magnitude of the line voltage at the source endof the line c) The total 3-phase real and reactive powersabsorbed by each load . d) The total 3-phase real and reactivepower losses in the line. e) The real power and reactive powersupplied at the source end of the line. f) If the second load isnow connected in Y-connection with the same impedance of 30-j60 Ωper phase, what would be the current per phase supplied by thesource
