A three-phase -connected generator is driving a balanced load such that each phase current is 12 A in magnitude. When I θa = 12 30° A, what are the polar expressions for the other phase currents?

A. I θb = 12 150° A, I θc = 12–90° A
B. I θb = 12120° A, I θc = 1230° A
C. I θb = 1230° A, I θc = 12120° A
D. I θb = 1290° A, I θc = 1290° A
Answer» B. I θb = 12120° A, I θc = 1230° A
