Three loads connected in parallel on a 480V line. The first is a 10hp full load induction motor (1hp = 745.7W) operating at a 0.6 lagging power factor. The second payload is a 5hp sync motor operating at 0.6 power factor up front. The third is a 7kW resistive load. Find the total line current and the Power Factor resulting from this association
