插件电阻具体讲解大全
? 插件电阻也称为电阻器 (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。下面我们来说说插件电阻具体讲解大全:?
? 固定电阻、可调电阻、特种电阻 (敏感电阻 )
? 氧化膜电阻
?
? 不能调节的 , 我们称之为定值电阻或固定电阻 , 而可以调节的 , 我们称之为可调电 阻 . 常见的可调电阻是滑动变阻器 , 例如收音机音量调节的装置是个圆形的滑动 变阻器 , 主要应用于电压分配的 , 我们称之为电位器
.
? 按制造材料有碳膜电阻、金属膜电阻、线绕电阻 , 无感电阻 , 薄膜电阻等 . ?

范文四：插件电阻的工作原理
插件电阻的工作原理
? 插件电阻可运用的很多产品上面，是一种运用广泛的电子部件，那我们如何理解插件电阻的工作原理呢?
?水泥电阻
? 在物理学中，用电阻来表示导体对电流阻碍作用的大小。导体的电阻越大，表示导体对电流的阻碍作用越大。不同的导体，电阻一般不同，电阻是导体本身的一种特性。电阻元件是对电流呈现阻碍作用的耗能元件。因为物质对电流产生的阻碍作用，所以称其该作用下的电阻物质。电阻将会导致电子流通量的变化，电阻越小，电子流通量越大，反之亦然。
?
? 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。
?
? 电阻的主要物理特征是变电能为热能，也可说它是一个耗能元件，电流经过它就产生内能。电阻在电路中通常起分压、分流的作用。对信号来说，交流
与直流信号都可以通过电阻。
