Finally, we saw how to measure voltage and current in a real circuit using voltmeters and ammeters.

后，我们了解了如何使用表和表测量实际路中的和。

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

这被称为表，通过与路串联来测量安。

Attaching the ammeter, a device with near-zero resistance, in parallel with another resistor, will cause nearly all the current to run through the ammeter, possibly damaging it.

将表（一种阻接近零的设备）与另一个阻器并联将允许几乎所有过表，可能导致损坏。
