Today, we’re going to build some basic circuits out of resistors and batteries to figure out how they react and change, depending on their configuration.

今天，我们将用电阻器和电池构建一些基本电路， 以弄清楚它们如何反应和变化， 具体取决于它们的配置。

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。

If you connect a battery to a basic circuit that contains only a capacitor, the battery causes charge to move from one plate to the other, through the conductive wire.

如果电池连接到包含电容器的初级电路， 它通过导线将电荷从一个板移动到另一个板。
