电流表、电压表是初中物理实验中两个重要仪表。它不仅可以测量电路中的电流、电压,还可以用来检查电路中的故障。电路中的故障通常为断路和短路。
Ammeter, voltmeter is a junior high school physics experiment two important instruments. It can not only measure the current in the circuit, the voltage, but also can be used to check the circuit fault. Faults in the circuit are usually open and shorted.
