Now, for example, if you've done physics, you'll know that a series circuit looks something like this.

例如，如果你学过物理，你会知道串联电路看起来像这样。

So, for a series connection, the current is the same for all resistors, and the voltage drop changes.

因此对于串联电路，所有电阻器的电流相同，并且电压降会发生变化。

This is known as an ammeter, and it measures the current in Amperes by connecting in series with the circuit.

这被称为电流表，通过与电路串联来培电流。

Now what happens when you add an identical light bulb in a series connection?

当您在串联电路中添加相同的灯泡时会发生什么？

We discussed both series and parallel circuit configurations, and how the laws of conservation affect the current and voltage for each.

我们讨论了串联和并联电路配置，以及守恒定律如何影响每种配置的电流和电压。
