So to get a handle on how inductors work, let's first consider one in a DC circuit.

因此，要了解电感器的工作原理， 让我们首先考虑直流电路中的电感器。

Typically, the voltage source in a DC circuit is unchanging, so the current will be constant, too.

通常，直流电路中的电压源是 不变的，因此电流也是恒定的。

These are DC circuits, with resistors in series and parallel formations.

这些是直流电路，串联电阻 和平行编队。

And what happens when we add capacitors into the mix, with resistors in our DC circuits?

当我们将电容器添加到混合物中时会发生什么 ，在我们的直流电路中添加电阻器？

In a DC circuit, a capacitor is useful for storing charge temporarily, then releasing it again later on.

在直流电路中，电容器可用于暂时存储电荷，然后再将其释放。

We’ll talk about currents that aren’t so constant later on, but for now, everything we deal with will be a DC circuit.

稍后我们将讨论不太恒定的电流， 但现在，我们处理的一切都将是直流电路。

They then took them to the DC circuit, which for complicated reason is where you go when you're pissed off at the SEC.

然后他们把它们带到了 DC 电路，由于复杂的原因， 当你对 SEC 生气时， 你就会去那里。

Today, we saw how circuit analysis can be used on any series and parallel configuration of resistors in a DC circuit.

今天我们看到了如何将电路分析用于直流电路中电阻的任何串联和并联配置。

We'll talk about currents that aren't so constant later on, but for now, everything we deal with will be a DC circuit.

稍后我们将讨论不太恒定的电流，但现在，我们要处理的只是直流电路。

We also discussed how capacitors function in a typical DC circuit and the ways they behave when combined in series and parallel connections.

我们还讨论了电容器在典型直流电路中的作用以及它们在串联和并联连接时的行为方式。

By now, thanks to our lesson on circuit analysis – and previous Crash Course Physics episodes – you know your way around a basic DC circuit.

到现在为止，多亏了我们关于电路分析的课程——以及之前的物理速成课程——你知道了基本直流电路的方法。

For example, what happens when there are multiple batteries, connected in parallel? And what happens when we add capacitors into the mix, with resistors in our DC circuits?

例如，当有多个电池并联连接时会发生什么情况？当我们在直流电路中添加电容器和电阻器时会发生什么？

But you can only take this equation for DC circuits so far, before you have to start making some serious changes for it to help you figure out AC circuits.

但是到目前为止，您只能将这个方程式用于直流电路，然后才能开始对其进行一些重大更改以帮助您计算出交流电路。
