A 120 V branch circuit has a 134 ft length and feeds a load drawing 25 A. Using a copper conductor with 2.5 mm^2 cross-section (approx. resistance ≈ 0.007 Ω/m), calculate the approximate voltage drop (round-trips length = 81.6 m).

• A. R ≈ 0.571 Ω; V_drop ≈ 14.3 V; percent drop ≈ 11.9%
• B. R ≈ 0.571 Ω; V_drop ≈ 7.1 V; percent drop ≈ 5.9%
• C. R ≈ 0.857 Ω; V_drop ≈ 21.4 V; percent drop ≈ 17.8%
• D. R ≈ 1.14 Ω; V_drop ≈ 28.5 V; percent drop ≈ 23.8%

Answer: (A)
