A three-phase motor is connected to a three-phase line that has an abc phase sequence and is supplied by a 15A current at a 0.85 lagging power factor. If a single-phase motor withdrawing 5A current at a 0.707 lagging power factor is connected across lines a and b of the three-phase power line, determine the total current in each lin
