Jul 30, 1999 · A 3-phase distribution line supplying this load has an impedance of 10+j5 ohms per phase. Calculate the currents drawn by each load (magnitude and phase). Indicate the power factor of each load. Remember that non-unity power factors must also include whether they are lagging or leading. What is the power factor of the entire load?
