電容器，通常簡稱其容納電荷的本領為電容，用字母C表示。定義1：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。電容器是電子設備中大量使用的電子元件之一，廣泛應用于電路中的隔直通交，耦合，旁路，濾波，調諧回路， 能量轉換，控制等方面。定義2：電容器，任何兩個彼此絕緣且相隔很近的導體（包括導線）間都構成一個電容器。簡單的電容器是由兩端的極板和中間的絕緣電介質（包括空氣）構成的。通電后，極板帶電，形成電壓（電勢差），但是由于中間的絕緣物質，所以整個電容器是不導電的。不過，這樣的情況是在沒有超過電容器的臨界電壓（擊穿電壓）的前提條件下的。我們知道，任何物質都是相對絕緣的，當物質兩端的電壓加大到一定程度后，物質是都可以導電的，我們稱這個電壓叫擊穿電壓。電容也不例外，電容被擊穿后，就不是絕緣體了。當電容器接通電源以后,在電場力的作用下,與電源正極相接電容器極板的 自由電子將經過電源移到與電源負極相接的極板下, 正極由于失去負電荷而帶正電, 負 極由于獲得負電荷而帶負電,正,負極板所帶電荷大小相等,符號相反.
