LISTRIK DINAMIS• Rangkaian DC
R₂, R₃ dan R₄ tersusun paralel
1/R₂₃₄ = 1/R₂ + 1/R₃ + 1/R₄
1/R₂₃₄ = 1/12 + 1/15 + 1/10
1/R₂₃₄ = (5 + 4 + 6) / 60
R₂₃₄ = 60/15 = 4 ohm
R₁ dan R₂₃₄ tersusun seri
R₁₂₃₄ = R₁ + R₂₃₄
R₁₂₃₄ = 11 + 4
R₁₂₃₄ = 15 ohm
V = i R₁₂₃₄
45 = i • 15
i = 3 A
i = i₂ + i₃ + i₄
i₂ : i₃ : i₄ = 1/R₂ : 1/R₃ : 1/R₄
i₂ : i₃ : i₄ = 1/12 : 1/15 : 1/10
i₂ : i₃ : i₄ = 5 : 4 : 6
i₄ = 6/15 × 3 A
i₄ = 1,2 A ✅
——
catatan :
i₁ = 3 A
i₂ = 1 A
i₃ = 0,8 A
i₄ = 1,2 A
