A delta-connected source supplies power to a wye-connected load in a three-phase balanced system. Given that the line impedance is 2 + j1 ? per phase while the load impedance is 6 + j4 ? per phase, find the magnitude of the line voltage at the load. Assume the source phase voltage Vab = 208?0? V rms.
