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

最后，解如何使用电表和电流表实际电路中的电和电流。

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，通过与电路串联安培电流。

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.

将电流表（一种电阻接近零的设备）与另一个电阻器并联将允许几乎所有电流流过电流表，可能导致损坏。
