Capacitors

电容器

Capacitance is typified by a parallel plate arrangement and is defined in terms of charge storage:

电容通常由平行板结构体现,并且以电荷存储来定义:

A battery will transport charge from one plate to the other until the voltage produced by the charge buildup is equal to the battery voltage.

电池会将电荷从一个极板运输到另一个极板,直到由电荷积累产生的电压等于电池电压。

where

  • Q = magnitude of charge stored on each plate.
    Q 是两个极板上所储存电荷的大小。
  • V = voltage applied to the plates.
    加在板上的电压V。

Charge on Series Capacitors

串联电容器的电荷

Since charge cannot be added or taken away from the conductor between series capacitors, the net charge there remains zero. As can be seen from the diagram, that constrains the charge on the two capacitors to be the same in a DC situation. This charge Q is the charge you get by calculating the equivalent capacitance of the series combination and multiplying it by the applied voltage V.

由于在串联电容器之间无法添加或移除电荷,该导体上的净电荷保持为零。如图所示,在直流情况下,这会迫使两个电容器上的电荷相等。该电荷Q可通过计算串联组合的等效电容并乘以施加的电压V来获得。

You store less charge on series capacitors than you would on either one of them alone with the same voltage!

在串联电容器中,你存储的电荷量比单独使用每个电容器时在相同电压下存储的要少!

Does it ever make sense to put capacitors in series? You get less capacitance and less charge storage than with either alone. It is sometimes done in electronics practice because capacitors have maximum working voltages, and with two "600 volt maximum" capacitors in series, you can increase the working voltage to 1200 volts.

在任何情况下把电容串联都有意义吗?你得到的电容和存储的电荷都比单独使用时少。在电子实践中有时会这样做,因为电容器有最大工作电压,用两个标称最大工作电压为600伏的电容器串联,可以将工作电压提高到1200伏。
