A three-phase ‚à Ü-connected generator is driving a balanced load such that each phase current is 12 A in magnitude. When I Œ∏a = 12 ‚à †30¬∞ A, what are the polar expressions for the other phase currents?~!

A. I Œ∏b = 12 ‚à †150¬∞ A, I Œ∏c = 12 ‚à †-90¬∞ A
B. I Œ∏b = 12 ‚à †120¬∞ A, I Œ∏c = 12 ‚à †30¬∞ A
C. I Œ∏b = 12 ‚à †30¬∞ A, I Œ∏c = 12 ‚à †120¬∞ A
D. I Œ∏b = 12‚à †90¬∞ A, I Œ∏c = 12 ‚à †90¬∞ A
Answer» B. I ≈í‚àèb = 12 ‚Äö√ ‚Ä 120¬¨‚àû A, I ≈í‚àèc = 12 ‚Äö√ ‚Ä 30¬¨‚àû A
