电阻器（Resistor）在日常生活中一般直接称为电阻。是一个限流元件，将电阻接在电路中后，电阻器的阻值是固定的一般是两个引脚，它可限制通过它所连支路的电流大小。阻值不能改变的称为固定电阻器。阻值可变的称为电位器或可变电阻器。理想的电阻器是线性的，即通过电阻器的瞬时电流与外加瞬时电压成正比。用于分压的可变电阻器。在裸露的电阻体上，紧压着一至两个可移金属触点。触点位置确定电阻体任一端与触点间的阻值。

电阻器出现故障的时候，怎么样来检测的方法与经验，毫欧电子分享具体步骤如下：

●固定电阻器的检测

A将两表笔（不分正负）分别与电阻的两端引脚相接即可测出实际电阻值。为了提高测量精度，应根据被测电阻标称值的大小来选择量程。由于欧姆挡刻度的非线性关系，它的中间一段分度较为精细，因此应使指针指示值尽可能落到刻度的中段位置，即全刻度起始的20%~80%弧度范围内，以使测量更准确。根据电阻误差等级不同。读数与标称阻值之间分别允许有±5%、±10%或±20%的误差。如不相符，超出误差范围，则说明该电阻值变值了。

B注意：测试时，特别是在测几十kΩ以上阻值的电阻时，手不要触及表笔和电阻的导电部分；被检测的电阻从电路中焊下来，至少要焊开一个头，以免电路中的其他元件对测试产生影响，造成测量误差；色环电阻的阻值虽然能以色环标志来确定，但在使用时最好还是用万用表测试一下其实际阻值。

●水泥电阻器的检测

检测水泥电阻的方法及注意事项与检测普通固定电阻完全相同。

●熔断电阻器的检测

在电路中，当熔断电阻器熔断开路后，可根据经验作出判断：若发现熔断电阻器表面发黑或烧焦，可断定是其负荷过重，通过它的电流超过额定值很多倍所致；如果其表面无任何痕迹而开路，则表明流过的电流刚好等于或稍大于其额定熔断值。对于表面无任何痕迹的熔断电阻器好坏的判断，可借助万用表R×1挡来测量，为保证测量准确，应将熔断电阻器一端从电路上焊下。若测得的阻值为无穷大，则说明此熔断电阻器已失效开路，若测得的阻值与标称值相差甚远，表明电阻变值，也不宜再使用。在维修实践中发现，也有少数熔断电阻器在电路中被击穿短路的现象，检测时也应予以注意。

解析电阻的组成与分类

物体对电流的这种阻碍作用，称为该物体的电阻。电阻元件的电阻值大小一般与温度，材料，长度，还有横截面积有关，衡量电阻受温度影响大小的物理量是温度系数，其定义为温度每升高1℃时电阻值发生变化的百分数。本文毫欧电子来给大家解析电阻的组成与分类。

电阻相关知识分享

电荷在导体中运动时，会受到分子和原子等其他粒子的碰撞与摩擦，碰撞和摩擦的结果形成了导体对电流的阻碍，这种阻碍作用最明显的特征是导体消耗电能而发热（或发光）。物体对电流的这种阻碍作用，称为该物体的电阻。
