R₁ = R₂ = R₃ = R₄ = R₅ = R₆ = R₇ = R₈ = R₉ = R₁₀ = R = 120 Ω

Hambatan pengganti untuk resistor 7,8,9,10 :

1/Rₚ₁ = 1/R₇ + 1/R₈ + 1/R₉ + 1/R₁₀

1/Rₚ₁ = 1/R + 1/R + 1/R + 1/R

1/Rₚ₁ = 4/R

Rₚ₁ = R/4

Rₚ₁ = 120/4 = 30 Ω

Hambatan pengganti untuk resistor 4,5,6 :

1/Rₚ₂ = 1/R₄ + 1/R₅ + 1/R₆

1/Rₚ₂ = 1/R + 1/R + 1/R

1/Rₚ₂ = 3/R

Rₚ₂ = R/3

Rₚ₂ = 120/3 = 40 Ω

Hambatan pengganti untuk resistor 2,3 :

Rₚ₃ = (R₂ R₃) / (R₂ + R₃)

Rₚ₃ = R² / 2R

Rₚ₃ = 120/2 = 60 Ω

Hambatan pengganti total :

Rₜₒₜₐₗ = R₁ + Rₚ₁ + Rₚ₂ + Rₚ₃

Rₜₒₜₐₗ = 120 + 30 + 40 + 60

Rₜₒₜₐₗ = 250 Ω ✔
