电容器，通常简称其容纳电荷的本领为电容，用字母c表示。定义1：电容器，顾名思义，是‘装电的容器’，是一种容纳电荷的器件。英文名称：capacitor。电容器是电子设备中大量使用的电子元件之一，广泛应用于电路中的隔直通交，耦合，旁路，滤波，调谐回路， 能量转换，控制等方面。定义2：电容器，任何两个彼此绝缘且相隔很近的导体（包括导线）间都构成一个电容器。
电容与电容器不同。电容为基本物理量，符号c，单位为f（法拉）。
通用公式c=q/u平行板电容器公式：板间电场强度e=u/d ，电容器电容决定式 c=εs/4πkd
随着电子信息技术的日新月异，数码电子产品的更新换代速度越来越快，以平板电视（lcd和pdp）、笔记本电脑、数码相机等产品为主的消费类电子产品产销量持续增长，带动了电容器产业增长。
定义：是由两块金属电极之间夹一层绝缘电介质构成。当在两金属电极间加上电压时，电极上就会存储电荷，所以电容器是储能元件。任何两个彼此绝缘又相距很近的导体，组成一个电容器。平行板电容器由电容器的极板和电介质组成 [1] 。
特点：
1.它具有充放电特性和阻止直流电流通过，允许交流电流通过的能力。
2.在充电和放电过程中，两极板上的电荷有积累过程，也即电压有建立过程，因此，电容器上的电压不能突变。

电容器的充电：两板分别带等量异种电荷，每个极板带电量的值叫电容器的带电量。
电容器的放电：电容器两极正负电荷通过导线中和。在放电过程中导线上有短暂的电流产生。
电容充电过程
电容充电过程
3.电容器的容抗与频率、容量之间成反比。即分析容抗大小时就得联系信号的频率高低、容量大小 [1] 。
平行板电容器的电容公式 [1] ：
介电常数真空εr=1，k为静电力常量，s为两板正对面积，d为两板间距离。
说明：平行板电容器内的电场是匀强电场.

电容器，通常简称其容纳电荷的本领为电容，用字母c表示。定义1：电容器，顾名思义，是‘装电的容器’，是一种容纳电荷的器件。英文名称：capacitor。电容器是电子设备中大量使用的电子元件之一，广泛应用于电路中的隔直通交，耦合，旁路，滤波，调谐回路， 能量转换，控制等方面。定义2：电容器，任何两个彼此绝缘且相隔很近的导体（包括导线）间都构成一个电容器。
电容与电容器不同。电容为基本物理量，符号c，单位为f（法拉）。

随着电子信息技术的日新月异，数码电子产品的更新换代速度越来越快，以平板电视（lcd和pdp）、笔记本电脑、数码相机等产品为主的消费类电子产品产销量持续增长，带动了电容器产业增长。
定义：是由两块金属电极之间夹一层绝缘电介质构成。当在两金属电极间加上电压时，电极上就会存储电荷，所以电容器是储能元件。任何两个彼此绝缘又相距很近的导体，组成一个电容器。平行板电容器由电容器的极板和电介质组成 [1] 。
特点：
1.它具有充放电特性和阻止直流电流通过，允许交流电流通过的能力。
2.在充电和放电过程中，两极板上的电荷有积累过程，也即电压有建立过程，因此，电容器上的电压不能突变。

电容器的充电：两板分别带等量异种电荷，每个极板带电量的值叫电容器的带电量。
电容器的放电：电容器两极正负电荷通过导线中和。在放电过程中导线上有短暂的电流产生。

3.电容器的容抗与频率、容量之间成反比。即分析容抗大小时就得联系信号的频率高低、容量大小 [1] 。
平行板电容器的电容公式 [1] ：
介电常数真空εr=1，k为静电力常量，s为两板正对面积，d为两板间距离。
说明：平行板电容器内的电场是匀强电场.
