Question

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?

Options:

A . I θb = 12 ∠150° A, I θc = 12 ∠-90° A

B . I θb = 12 ∠120° A, I θc = 12 ∠30° A

C . I θb = 12 ∠30° A, I θc = 12 ∠120° A

D . I θb = 12∠ 90° A, I θc = 12 ∠90° A

Answer: Option A
