電容器的作用？

1.電容器(qi)用(yong)于(yu)存儲電量以便高速(su)釋放。閃光燈用(yong)到的就是這一功(gong)能。大型激(ji)光器(qi)也使用(yong)此(ci)技(ji)術(shu)來獲得非常明亮的瞬時閃光效果。

2.電容器(qi)還可(ke)以消除脈動。如果傳導直流電壓(ya)的線(xian)路含(han)有脈動或尖峰，大容量電容器(qi)可(ke)以通過(guo)吸收(shou)波峰和填充(chong)波谷來使電壓(ya)變得平穩。

3.電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)可以阻(zu)隔直流(liu)(liu)(liu)。如果將一(yi)個(ge)較(jiao)小的電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)連接到電(dian)(dian)(dian)(dian)(dian)池(chi)上，則(ze)在電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)充(chong)電(dian)(dian)(dian)(dian)(dian)完成(cheng)后(電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)容(rong)(rong)量較(jiao)小時，瞬間(jian)(jian)即可完成(cheng)充(chong)電(dian)(dian)(dian)(dian)(dian)過程)，電(dian)(dian)(dian)(dian)(dian)池(chi)的兩極之間(jian)(jian)將不再有電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)通(tong)(tong)過。然而，任(ren)何(he)交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(AC)信號都(dou)可以暢通(tong)(tong)無阻(zu)地(di)流(liu)(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)。其(qi)原因是隨著交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的波動，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)器(qi)不斷(duan)地(di)充(chong)放電(dian)(dian)(dian)(dian)(dian)，就好像交流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)在流(liu)(liu)(liu)動一(yi)樣(yang)。

4. 電容器(qi)與(yu)電感器(qi)一起使用(yong)，跌(die)落式熔斷器(qi)絕緣護(hu)罩，可構成振蕩器(qi)。

電流(liu)互感器(qi)的(de)工(gong)作原理和變(bian)壓器(qi)的(de)基(ji)本原理一(yi)樣，電流(liu)互感器(qi)一(yi)、二次電流(liu)之間(jian)的(de)關(guan)系為(wei):
