The measuring range ammeter can be made by user's.
All the current flowing in the circuit must pass through the ammeter.
The permanent magnet meter can be used as an ammeter or a voltmeter.
The device quantitatively demonstrating Amp è re force consists of single beam balance , magnet, ammeter, and rheostat.
利用单盘天平、磁极 、 教学用的电表 、 变阻器等器材自制了安培力定量演示装置.
The design principle and constitution of remote concentrated ammeter reading system is communication software is described.
该系统不仅能抄收和设置电子式电度表,还能对普通电表加装采集模块后进行集中管理.
