Extracted text: Q3: A 3- phase transmission line having impedance of (2+j6) ohm the supply voltage is 350-volt 50 Hz. load connected consist of three impedance each (5+j 10) ohm. Determine the efficiency of the system when the load is (i) delta connected and (ii) star connected. Based on the results, state your opinion which connection give the best performance and explain you answer.
