O'tkazgich qarshiligi va uning temperaturaga bog'liqligi

Temperatura ortishi natijasida metall o'tkazgich qarshiligining o'zgarishini kuzatish

R = R0 [1 + α(T - T0)]
ΔR = R0αΔT
I — tok yo'nalishi
T = 20 °C
Atomlar kuchsiz tebranmoqda — elektronlar nisbatan erkin harakatlanmoqda.
T = 20 °C
R0 = 20 Ω
α = 0.0040 1/°C
Boshlang'ich temperatura
T0 = 20 °C
Temperatura o'zgarishi
ΔT = 0 °C
Qarshilikning o'zgarishi
ΔR = 0 Ω
Yangi qarshilik
R = 20 Ω
1. Temperatura T ortadi
2. Kristall panjara tebranishi kuchayadi
3. Elektronlarning to'qnashuvlari ortadi
4. O'tkazgich qarshiligi R ortadi
Avtomatik hisoblash
R = R0 [1 + α(T - T0)]
R = 20 [1 + 0.0040 ( 20 - 20)]
R = 20.00 Ω
