Magnetic Saturation and the 100 Amp DC Current Transformer
An Alternative to Using a Series Shunt
For most of us, measuring DC current means putting an ammeter or low resistance current shunt in the line. But now, you can build an adapter that can be used with your voltmeter and will measure 100 amps DC.

From the Nuts & Volts Webstore
Teardowns: Learn How Electronics Work by Taking Them Apart
This one's by Nuts & Volts' own Bryan Bergeron, so you know it has to be good! Right?
Remember taking things apart as a kid just to see how they worked? Only they didn't quite go back together the same way and never actually worked the same again. Well here, Bryan takes his own stuff apart so you don't have to break yours and shows you what everything inside does, right down to the last resistor! He'll also recommend some modifications and ways to use the parts for other things. It doesn't get any better than that!
