電(dian)(dian)(dian)(dian)感(gan)在(zai)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中的(de)基本用途：濾波(bo)器Du、振蕩、延遲、陷波(bo)；圖像語句之(zhi)和：直(zhi)流(liu)(liu)(liu)、刀電(dian)(dian)(dian)(dian)阻交(jiao)流(liu)(liu)(liu)；直(zhi)流(liu)(liu)(liu)：所(suo)謂直(zhi)流(liu)(liu)(liu)指的(de)是電(dian)(dian)(dian)(dian)感(gan)在(zai)直(zhi)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中的(de)作用，不起任何作用；電(dian)(dian)(dian)(dian)阻AC：在(zai)交(jiao)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中，電(dian)(dian)(dian)(dian)感(gan)會有(you)阻抗，即整個XL電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)會變小，這在(zai)一(yi)定程度上(shang)阻礙了交(jiao)流(liu)(liu)(liu)。在(zai)電(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)中，電(dian)(dian)(dian)(dian)感(gan)線(xian)圈作用于(yu)交(jiao)流(liu)(liu)(liu)限(xian)流(liu)(liu)(liu)。它可(ke)以(yi)形成高通或(huo)低通濾波(bo)器，相移電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)和帶(dai)有(you)電(dian)(dian)(dian)(dian)阻或(huo)電(dian)(dian)(dian)(dian)容器的(de)諧振電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)。

　　電(dian)感的作(zuo)用是阻(zu)礙電(dian)流(liu)的變化，但(dan)這種影響不同(tong)于阻(zu)礙電(dian)流(liu)流(liu)動(dong)的電(dian)阻(zu)效應。電(dian)阻(zu)阻(zu)礙電(dian)流(liu)流(liu)動(dong)的影響主要表現在電(dian)能消耗(hao)上，而電(dian)感阻(zu)礙電(dian)流(liu)的變化純粹(cui)是為了(le)不讓電(dian)流(liu)發生變化。

　　當電(dian)(dian)(dian)流(liu)增(zeng)大時(shi)，電(dian)(dian)(dian)感(gan)會阻(zu)(zu)礙(ai)電(dian)(dian)(dian)流(liu)的增(zeng)大，當電(dian)(dian)(dian)流(liu)減(jian)小時(shi)，電(dian)(dian)(dian)感(gan)會阻(zu)(zu)礙(ai)電(dian)(dian)(dian)流(liu)的減(jian)小。電(dian)(dian)(dian)感(gan)阻(zu)(zu)礙(ai)電(dian)(dian)(dian)流(liu)的變(bian)化(hua)，不(bu)消(xiao)耗電(dian)(dian)(dian)能。當電(dian)(dian)(dian)流(liu)增(zeng)大時(shi)，它(ta)會暫時(shi)以磁場的形式儲(chu)存(cun)電(dian)(dian)(dian)能。當電(dian)(dian)(dian)流(liu)減(jian)小時(shi)，它(ta)也(ye)釋(shi)放出磁場的能量(liang)。因此，它(ta)阻(zu)(zu)礙(ai)了電(dian)(dian)(dian)流(liu)的變(bian)化(hua)。
