Three-Phase Systems in Power Applications

Q1:

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

ANS:A - I θb = 12 150° A, I θc = 12–90° A

It's a very good explanation.

Thank you @Aashish.
