LISTRIK DINAMIS

16][
i = 16 A
i₁ : i₂ : i₃ = 1 : 3 : 4

Menurut Hk. I Kirchoff
i₁ + i₂ + = i


Besar i₃
i₃ = [4 / (1+3+4)] × (16 A)
i₃ = ½ × (16 A)
i₃ = 8 A ✓
jawaban [C]


18][
R₁ = 4 ohm
R₂ = 5 ohm
R₃ = R₄ = R₅ = 2 ohm

R₃, R₄, R₅ tersusun paralel
1/Rₚ = 1/R₃ + 1/R₄ + 1/R₅
1/Rₚ = 1/2 + 1/2 + 1/3
1/Rₚ = 3/2
Rₚ = ⅔ ohm

R₁ ,R₂, Rₚ tersusun seri
R = R₁ + R₂ + Rₚ
R = 4 + 5 + ⅔
R = 9⅔ ohm ✓
