1.電容通常簡(jiǎn)稱其容納電荷的本領(lǐng)為電容，用字母C表示。描述一：電容器，顧名思義，是‘裝電的容器’，是一種容納電荷的器件。英文名稱：capacitor。電容器是電子設(shè)備中大量使用的電子元件之一，廣泛應(yīng)用于電路中的隔直通交，耦合，旁路，濾波，調(diào)諧回路，能量轉(zhuǎn)換，控制等方面。描述二：電容器，任何兩個(gè)彼此絕緣且相隔很近的導(dǎo)體（包括導(dǎo)線）間都構(gòu)成一個(gè)電容器。描述三.通用公式C=Q/U平行板電容器公式：板間電場(chǎng)強(qiáng)度E=U/d，電容器電容決定式C=εS/4πkd2.作用在直流電路中，電容器是相當(dāng)于斷路的。電容器是一種能夠儲(chǔ)藏電荷的元件，也是常用的電子元件之一。在交流電路中，因?yàn)殡娏鞯姆较蚴请S時(shí)間成一定的函數(shù)關(guān)系變化的。而電容器充放電的過(guò)程是有時(shí)間的，這個(gè)時(shí)候，在極板間形成變化的電場(chǎng)，而這個(gè)電場(chǎng)也是隨時(shí)間變化的函數(shù)。實(shí)際上，電流是通過(guò)電場(chǎng)的形式在電容器間通過(guò)的。電容器灌膠是為了保護(hù)電容，但也不是所有電容都需要灌封膠保護(hù)，可變電容、微調(diào)電容是空氣或聚酯薄膜絕緣，不能灌封的。大型電力電容，需用絕緣。半導(dǎo)體電容是用專門的電解液計(jì)量泵注入，目前我還不清楚是否需要灌封，請(qǐng)懂的朋友下方留言，不吝賜教，謝謝！常州RFM電容器定做AFM電容器質(zhì)量哪家好，歡迎來(lái)電咨詢，無(wú)錫市錫容電力電器有限公司。</p><div
