2.7. Two impedances, Z₁ = 0.8+j5.6 and Z₂ = 8-j16 f, and a single-phase motor are connected in parallel across a 200-V rms, 60-Hz supply as shown in Figure 2.23. The motor draws 5 KVA at 0.8 power factor lagging. + 7 200/0° V 0.8 j5.6 -163 Is M S35 KVA at 0.8 PF lag (a) Find the complex powers S₁, S₂ for the two impedances, and Sy for the motor. (b) Determine the total power taken from the supply, the supply current, and the overall power factor. (c) A capacitor is connected in parallel with the loads. Find the kvar and the capacitance in µF to improve the overall power factor to unity. What is the new line current?
