Components and Methods for Current Measurement
This indirect current measurement method requires a changing current - such as an AC, transient current, or switched DC - to provide a changing magnetic field that is magnetically coupled into the secondary windings. The secondary measurement voltage can be scaled according to the turns ratio between the primary and secondary windings.

How do batteries work? A simple introduction
Measuring batteries. When the battery dies in your flashlight, you go out and buy a replacement. Typically, you just buy one the same size, so it''ll fit inside the case. But batteries are like boxes: just as bigger boxes can hold more stuff, so the size of a battery is actually a measurement of how much electrical energy it can store. Why?
