apabila kurang jelas tanyakan di komentar ya
R₂ = 1,25.R
Penjelasan:
Kedua kawat jenisnya sama
ρ₁ = ρ₂ = ρ
L1 = 2 m
A1 = 0,2 cm²
R₁ = R
L2 = 0,5 m
A2 = 0,04 m
R₂ = ?
R₁ : R₂ = ρ.L1/A1 : ρ.L2/A2
R : R₂ = L1/A1 : L2/A2
R : R₂ = 2/0,2 : 0,5/0,04
R : R₂ = 10 : 12,5
10.R₂ = 12,5 . R
R₂ = 12,5/10 = 1,25.R
