|resistance coefficient/specific resistance;電阻系數
電阻率（electrical resistivity）是表征材料阻礙電流流動能力的固有物理屬性，用希臘字母ρ表示。其定義為在特定溫度下，由該材料制成的單位截面積、單位長度的均勻導體所具有的電阻值。電阻率是材料本身的特性，與導體的形狀和尺寸無關，僅取決于材料的種類、成分和溫度。
核心概念解析：
參考來源：
Electrical resistivity（電阻率）是描述材料阻礙電流流動能力的物理性質。以下是詳細解釋：
單位 國際單位制中為歐姆·米（Ω·m），也常用Ω·cm（1 Ω·m = 100 Ω·cm）。
與電導率的關系 電阻率是電導率（$sigma$）的倒數，即$sigma = 1/rho$。
影響因素
例如，銅的電阻率極低（約$1.68 times 10^{-8}$ Ω·m），使其成為高效導電材料；而石英玻璃的電阻率高達約$10^{16}$ Ω·m，適合用作絕緣體。
