An inductive load with impedance Z is connected to a single-phase 50Hz, 230V AC supply as shown in Figure 1. If the load draws 7.5 kW at a power factor of 0.65 lagging: i) Determine the supply current (/) in complex form. ii) Determine the supply apparent power (S) in complex form. iii) Determine the load impedance (Z). iv) Draw the power triangle showing numerical values of the complex power. If a capacitor is connected in parallel across the load to correct the power factor to 0.9: v) Draw the power triangle of the compensated system. vi) Calculate the capacitor size (C). vii) Find the new supply current (/) in complex form. V=23020⁰0 Figure 1 N
