<p><span style="font-size: 14px"> </span>电感线圈是利用电磁感应的原理进行工作的器件。当有电流流过一根导线时，就会在这根导线的周围产生一定的电磁场，而这个电磁场的导线本身又会对处在这个电磁场范围内的导线发生感应作用。对产生电磁场的导线本身发生的作用，叫做“自感“，即导线自己产生的变化电流产生变化磁场，这个磁场又进一步影响了导线中的电流;对处在这个电磁场范围的其他导线产生的作用，叫?ldquo;互感“。那么电感线圈在电子线路中会又怎样的表现呢，一起来看看吧：</p>
<p> </p>
<p> <strong><a href="http://www.chenfeipower.com/product/">电感线圈</a></strong>在电子线路中基本用于两方面：</p>
<p> </p>
<p> 1，与电容电阻配合用于波形产生电路或频率选择电路?/p>
<p> </p>
<p> 2，在电流比较大且脉动比较大的场合串入电路内用作平波器。其它场合还有很多，比如日光灯中的镇流器，主要就是根据电感线圈两端电流不能突变当电流变化率过快时能产生很高反向电动势的原理做成的?/p>
