​铜的电阻率温度系数是多少呢?铜的电阻率温度系数定义是什么呢?我们先来纠正下铜的电阻率温度系数这个词。铜的电阻率温度系数其实正确的叫铜的电阻温度系数。下面介绍到的铜的电阻率温度系数就是指铜的电阻温度系数。铜的电阻率温度系数的定义:英文全称叫做temperaturecoefficientofresistance,简称就是TCR,表示的是电阻当温度改变1度时,电阻值的相对变化。铜的电阻率温度系数单位为ppm/℃,就是10E(-6)/℃。铜的电阻率温度系数大家可能很少接触到的。没关系,今天我们就为大家介绍下铜的电阻率温度系数的有关知识。

铜的电阻率温度系数:

1、定义式以下:TCR=dR/;

2、实际应用时,通常采取平均电阻温度系数,定义式以下:TCR(平均)=(R2-R1)/(R1*(T2-T1))=(R2-R1)/(R1*T)

其中R1--温度为t1时的电阻值,;

R2--温度为t2时的电阻值,。
