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

  1. Iθb = 12 ∠120° A, Iθc = 12 ∠30° A
  2. Iθb = 12 ∠150° A, Iθc = 12 ∠-90° A
  3. Iθb = 12 ∠90° A, Iθc = 12 ∠120° A
  4. Iθb = 12∠ 60° A, Iθc = 12 ∠90° A

Correct answer: 2. Iθb = 12 ∠150° A, Iθc = 12 ∠-90° A
