----------Diket :
Suhu awal, T1 = 15°C
Suhu akhir, T2 = 50°C
Beda suhu, ΔT = 35°C
Hambatan jenis, ρo = 1,67 x 10^-8 ohm.meter
Koef suhu, α = 0,0037 /°C
Tanya :
Hambatan jenis pada suhu akhir 50°C, ρ = __?
Jawab :
ρ = ρo.(1 + α.ΔT)
ρ = 1,67 x 10^-8•(1 + 0,0037•35)
ρ = 1,67 x 10^-8•(1 + 0,1295)
ρ = 1,67 x 10^-8•(1,1295)
ρ = 1,89 x 10^-8 ohm. Meter
