In the circuit of figure shown in the next slide, three impedances are 12 – j10 ohms, 10 + j20 ohms, and 15 + j0 ohms, connected between conductors a, b, c and the neutral “n” of a balanced 230 volts, 60 hertz, 3 phase, 4 wire, ABC system. Using Van as the reference vector, determine: a. Current in each impedance
