它(ta)們中(zhong)的(de)(de)大多數是由(you)固(gu)定(ding)容(rong)(rong)(rong)量制成的(de)(de)。可(ke)(ke)變(bian)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)；在一定(ding)容(rong)(rong)(rong)量規(gui)模內可(ke)(ke)自(zi)由(you)調(diao)節的(de)(de)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)，如； 收(shou)音(yin)機能(neng)夠手動調(diao)諧并用于頻道選擇。可(ke)(ke)變(bian)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)、可(ke)(ke)調(diao)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)也稱半可(ke)(ke)變(bian)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)； 在一定(ding)規(gui)模內可(ke)(ke)調(diao)電(dian)(dian)容(rong)(rong)(rong)，如； 瓷基微雕電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)和繞(rao)線電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi).不(bu)能(neng)說容(rong)(rong)(rong)量大的(de)(de)電(dian)(dian)容(rong)(rong)(rong)器(qi)(qi)(qi)(qi)有(you)極性.這是錯誤的(de)(de)。

例如，電(dian)力系統中用(yong)于(yu)相位角調整的電(dian)容(rong)器和用(yong)于(yu)啟(qi)動電(dian)網的消弧電(dian)容(rong)器有時具有大容(rong)量。但(dan)不(bu)廣(guang)泛。電(dian)解電(dian)容(rong)器不(bu)管(guan)其容(rong)量怎么都(dou)會被極(ji)化。

電容器和 avx鉭電容器不管其容量怎么都是極化的。 請注意這一點。油浸紙電容器； avx鉭電容能夠運用中性熱原油作為介電電容，多用于電力系統。 電容器分為固定電容、可變電容和可調電容三種。 繞線電容器是一種將金屬線繞在電介質上作為電極的電容器。 電極的面積能夠通過改動金屬線的匝數來調整容量的大小。
