A single phase line has an impedance of 8.4 + j11.2 Ω. The line feeds a load consisting of a resistor and an inductor connected in parallel as shown in Figure 1. The load is absorbing 30kVA at 0.6 power factor lagging. The load voltage is 1200Vrms.

(b) Supply current Ig and the supply voltage Vg,
(c) Total real and reactive power loss in the line.
