Three phase power transformer secondaries that are set up in a delta configuration do not have an earthing or grounding point. By contrast, a wye configuration of windings would provide such a point, ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A.

这个项目使用 3D 打印外壳测量放射性，带有 OLED 显示屏和锂离子电池。 项目是在我买了一个现成的 Geiger 计数器套件之后开始的。 我的整个想法是把这个套件放在一个 3D 打印的外壳中，这样完整的盖革计数器套件就可以手持了。最终结果如下图所示： 盖革计数 ...
