Hitunglah hambatan pengganti rangkaian hambatan berikut

LISTRIK DINAMIS
• Rangkaian Hambatan

R₁ dan R₂ tersusun seri
R₁₂ = R₁ + R₂
R₁₂ = 5 + 15 = 20 ohm

R₃ dan R₄ tersusun seri
R₃₄ = R₃ + R₄
R₃₄ = 10 + 10 = 20 ohm

R₁₂ dan R₃₄ tersusun paralel
1/R₁₂₃₄ = 1/R₁₂ + 1/R₃₄
1/R₁₂₃₄ = 1/20 + 1/20 = 2/20
R₁₂₃₄ = 20/2 = 10 ohm

R₁₂₃₄ dan R₅ tersusun seri
R₁₂₃₄₅ = R₁₂₃₄₅ + R₅
R₁₂₃₄₅ = 10 + 20 = 30 ohm

R₆ dan R₇ tersusun seri
R₆₇ = R₆ + R₇
R₆₇ = 15 + 15 = 30 ohm

R₁₂₃₄₅ dan R₆₇ tersusun paralel
1/R₁₂₃₄₅₆₇ = 1/R₁₂₃₄₅ + 1/R₆₇
1/R₁₂₃₄₅₆₇ = 1/30 + 1/30 = 2/30
R₁₂₃₄₅₆₇ = 30/2 = 15 ohm ✓
