LISTRIK DINAMIS

▶ Rangkaian Resistor

R₁ = 20 Ω

R₂ = 50 Ω

R₃ = 24 Ω

R₄ = 15 Ω

R₅ = 30 Ω

rangkaian jembatan wheatstone

tes kali silang

R₁ × R₄ = 300 Ω

R₂ × R₃ = 1200 Ω

R₁ × R₄ ≠ R₂ × R₃

gunakan rangkaian hambatan bantu

Ra = (R₁ × R₂) / (R₁ + R₂ + R₅)

Ra = (20 × 50) / (20 + 50 + 30)

Ra = 10 Ω

Rb = (R₁ × R₅) / (R₁ + R₂ + R₅)

Rb = (20 × 30) / (20 + 50 + 30)

Rb = 6 Ω

Rc = (R₂ × R₅) / (R₁ + R₂ + R₅)

Rc = (50 × 30) / (20 + 50 + 30)

Rc = 15 Ω

Rb₃ = Rb + R₃

Rb₃ = 6 + 24

Rb₃ = 30 Ω

Rc₄ = Rc + R₄

Rc₄ = 15 + 15  

Rc₄ = 30 Ω

Rb₃ dan Rc₄ terangkai paralel

Rp = (Rb₃ × Rc₄) / (Rb₃ + Rc₄)

Rp = (30 × 30) / (30 + 30)

Rp = 15 Ω

R.total = __ ?

hambatan pengganti total

R.total = Ra + Rp

R.total = 10 + 15

R.total = 25 Ω
