Example 2 — Y → Δ: Combine to remove central node Problem: Star resistances Ra = 5 Ω, Rb = 10 Ω, Rc = 15 Ω. Find equivalent delta resistor between nodes 1–2. Solution: S = Ra Rb + Rb Rc + Rc Ra = 5 10 + 10 15 + 15 5 = 50 + 150 + 75 = 275 Ω R12 = S / Rc = 275 / 15 ≈ 18.333 Ω R23 = 275 / Ra = 275 / 5 = 55 Ω R31 = 275 / Rb = 275 / 10 = 27.5 Ω
