This question is about 3 phase unbalanced delta power systems. the line voltage is 415v. each phase has a resistor, resistor 1 is 5ohms with an angle of 0 degrees, resistor 2 is 10ohms with angle of240 degrees and the 3rd phase it has a resistor of 15ohms with an angle of 120 degrees. what are the currents of each phase and the neutral current. please show conversion from polar form to right angular form if required. thanks
