我想問熱敏電阻器的電阻隨溫度上升而下降,那麼我想問"R=V/I"這條公式仍然適用於計算熱敏電阻器的電阻嗎? (我見R正比於V) 請解釋Thanks^^

✔ 最佳答案
There are some assumptions when using this equation R=V/i ~It should be assumed that the temperature is kept constant~
I think if you calculate the resistance by using 熱敏電阻器, other equation will be used rather than this one~
