The total copper cross sections in terms of current-carrying capacity for a single-phase and a three-phase 120 V system with effective load resistance of 15 Ω is given as

  1. Single-phase 16 A; three-phase 0 A
  2. Single-phase 16 A; three-phase 8 A
  3. Single-phase 32 A; three-phase 16 A
  4. Single-phase 8 A; three-phase 4 A

Correct answer: 2. Single-phase 16 A; three-phase 8 A
