电(dian)(dian)(dian)感线(xian)(xian)圈(quan)是(shi)由导线(xian)(xian)一(yi)(yi)圈(quan)一(yi)(yi)圈(quan)地绕在(zai)绝(jue)缘管(guan)上(shang)，导线(xian)(xian)彼此互相绝(jue)缘，而绝(jue)缘管(guan)可以是(shi)空心的，也可以包含铁芯或磁(ci)粉芯，简称电(dian)(dian)(dian)感。在(zai)电(dian)(dian)(dian)子制作中虽然使用得不是(shi)很多，但它们在(zai)电(dian)(dian)(dian)路中同样(yang)重要。电(dian)(dian)(dian)感器(qi)和电(dian)(dian)(dian)容器(qi)一(yi)(yi)样(yang)，也是(shi)一(yi)(yi)种(zhong)储能(neng)元件，它能(neng)把(ba)电(dian)(dian)(dian)能(neng)转(zhuan)变为磁(ci)场能(neng)，并在(zai)磁(ci)场中储存能(neng)量。电(dian)(dian)(dian)感器(qi)用符号L表示，它的基本单(dan)(dan)位(wei)是(shi)亨(heng)利（H），常用毫亨(heng)（mH）为单(dan)(dan)位(wei)。

      电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)是(shi)能(neng)够把电(dian)(dian)(dian)(dian)(dian)(dian)(dian)能(neng)转(zhuan)化(hua)为磁能(neng)而(er)存储起来的元件。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)的结构类(lei)似于变压器(qi)(qi)，但(dan)只(zhi)有一个绕(rao)组。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)具有一定的电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)，它只(zhi)阻碍(ai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的变化(hua)。如果(guo)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)在(zai)(zai)没有电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)通过(guo)的状态下(xia)(xia)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)接(jie)通时它将试图阻碍(ai)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)流(liu)过(guo)它;如果(guo)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)在(zai)(zai)有电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)通过(guo)的状态下(xia)(xia)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)断开时它将试图维持电(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不(bu)变。电(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)(gan)器(qi)(qi)又(you)称扼流(liu)器(qi)(qi)、电(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)、动态电(dian)(dian)(dian)(dian)(dian)(dian)(dian)抗器(qi)(qi)。

电感器的分类：

按电感形式分类：固(gu)定电感(gan)、可变电感(gan)。

按绕线结构分类：单(dan)层(ceng)线圈(quan)、多层(ceng)线圈(quan)、蜂房式线圈(quan)。

按导磁体性质分类：空(kong)芯(xin)线(xian)(xian)圈(quan)(quan)(quan)(quan)、铁氧体线(xian)(xian)圈(quan)(quan)(quan)(quan)、铁芯(xin)线(xian)(xian)圈(quan)(quan)(quan)(quan)、铜芯(xin)线(xian)(xian)圈(quan)(quan)(quan)(quan)。

按工作性质分类：天线(xian)(xian)(xian)线(xian)(xian)(xian)圈(quan)(quan)、振荡线(xian)(xian)(xian)圈(quan)(quan)、扼流线(xian)(xian)(xian)圈(quan)(quan)、陷波线(xian)(xian)(xian)圈(quan)(quan)、偏(pian)转线(xian)(xian)(xian)圈(quan)(quan)。

电感器的特性：

它经常和电容器一起工作，构成LC滤波器、LC振荡器等。另外，人们还利用电感的特性，制造了阻流圈、变压器、继电器等；电感器的特性恰恰与电容的特性相反，它具有阻止交流电通过而让直流电通过的特性。

收音机上就有不少电感线圈，几乎都是用漆包线绕成的空心线圈或在骨架磁芯、铁芯上绕制而成的。有天线线圈（它是用漆包线在磁棒上绕制而成的）、中频变压器（俗称中周）、输入输出变压器等等。

常用电感器：单层线圈、蜂房式线圈、铁氧体磁芯和铁粉芯线圈、铜芯线圈、色码电感器、阻流圈（扼流圈）、偏转线圈。
