So, for example if I read, what is the capacitance of biomembranes?

举个例子，如果我读到，生膜的容是多少？

Capacitance is unique in this way.

容在这方面是独一无二的。

And realize, we have  now begun our journey towards determining the capacitance of an ideal parallel plate capacitor.

并且意识到，我们现在已经开始确定理想平行板容器的容。

And that's why the full equation for capacitance includes a dielectric constant, K.

，全容方程包含一个常数 隔离，K。

So, how can you describe the equivalent capacitance of a circuit like this?

那么，如何描述这样 的路的等效容呢？

Therefore, you can factor out charge, and you’re left with the equation for equivalent capacitance of capacitors connected in series.

，可以排除荷， 剩下串联容器等效容的方程式。

So for series capacitors, the combined capacitance is less than the weakest individual capacitor.

对于串联容器，组合 容小于最弱的单个容器。

Therefore, you can factor out charge, and you're left with the equation for equivalent capacitance of capacitors connected in series.

，可以将荷分解，剩下的就是串联容器的等效容方程。

– unless you stick something between them, which actually increases the capacitance.

除非你在两者之间放置一些东西，否则会增加容量。

And that’s why the full equation for capacitance includes a dielectric constant, K. So dielectrics can help capacitors hold even more energy.

这就是为什么完整的容方程包括介常数 K。介质可以帮助容器保持更多的能量。

Well, if you have several capacitors connected in parallel, the overall capacitance of the circuit increases.

好吧，如果你有几个并联的容器，路的总容会增加。

So to find the equivalent capacitance in this case, just substitute in the charge equation (voltage-times-capacitance) for each voltage across the capacitors.

，要在这种情况下找到等效容，只需将容器两端的每个压代入荷方程（压乘以容）即可。

A dielectric is used to increase capacitance while preventing any charge from jumping from plate to plate.

绝缘体用于增加容量，同时 防止任何货从一个盘子跳到另一个盘子。

And once you've established the geometry of the plates, the capacitance does not change

一旦确定了两个板的几何形状，容就不会改变。

And you know that the charge held by each capacitor is equal to the capacitance times the voltage across each one.

而且知道每个容器所保持的荷等于容乘以每个容器上的压。

And it works because of two main electrical principles: electric potential energy and capacitance.

它根据两个气定律运行 两个主要的：容和势能。

Capacitance uses units of Farads, with one Farad equal to one Coulomb per Volt.

容以法拉为单位测量，其中一法拉等于 库仑超过伏特。

This value is known as capacitance – how much charge a capacitor is able to hold.

这个值被称为容，荷量 容器可以容纳。

So by inserting an insulating material into our capacitor, we've increased capacitance and can hold more charge, and thus energy, for the same amount of voltage.

通过在容器中引入绝缘材料，我们增加了容，我们能够 它在相同的张力下存储更多的荷和能量。

So by inserting an insulating material into our capacitor, we’ve increased capacitance and can hold more charge, and thus energy, for the same amount of voltage.

，通过在我们的容器中插入绝缘材料， 我们增加了容并且可以容纳更多的荷， 从而在相同的压下容纳更多的能量。
