Question

Besar hambatan pengganti rangkaian AB adalah?

Answer 1

R₁ = 3 ohm (kiri)
R₂ = 2 ohm (atas)
R₃ = 2 ohm (kanan)
R₄ = 4 ohm
R₅ = 2 ohm (kiri)
R₆ = 2 ohm (bawah)
R₇ = 3 ohm (kanan)
----------------------------------------------------------
Rs₁ = R₂ + R₃
Rs₁ = 2 + 2
Rs₁ = 4 ohm
----------------------------------------------------------
Rs₂ = R₅ + R₆
Rs₂ = 2 + 2
Rs₂ = 4 ohm
----------------------------------------------------------
1/Rp = 1/Rs₁ + 1/R₄ + 1/Rs₂
1/Rp = 1/4 + 1/4 + 1/4
1/Rp = 3/4
Rp = 4/3 ohm
----------------------------------------------------------
Rtotal = R₁ + Rp + R₇
Rtotal = 3 + 4/3 + 3
Rtotal = 9/3 + 4/3 + 9/3
Rtotal = 22/3 ohm

Semoga membantu :)
