A 3-phase, 7.5 V transformer has its high voltage winding connected in delta and the low voltage winding connected in star. If a load consisting of three impedances 12+ j(16) ohms are joined in delta across the low-voltage side, calculate (a) the kW delivered to the load, current in the (b) low and (c) high voltage windings
