    If a star source with Vll = 415v, is connected to a delta load with equal impedance of 18+j6 per phase, with line impedance of 1+j2 per phase, what would the line currents and currents in the load be as I am getting stuck with the conversion. Would they be the same or different? We have to give the currents in polar form?

    Consider that each AC line connects to a common point on a delta node where the current splits into either of two delta branches. Clearly the delta branch and line currents cannot be the same.
