Most battery chargers use nothing more than a series-pass regulator with current limiting. In solar-powered systems, you can't count on having sufficient head room to keep a series regulator alive, so ...

We often think of Ohm's Law as V = I × R. That's not really Ohm's law, but we'll use that relationship today to measure V = I × R for some large currents. Specifically, I need to design a good 1-mΩ ...

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and even more ...

Riedon, a specialist manufacturer of cutting-edge power and precision resistors, has expanded its portfolio of precision current shunts to provide one of the broadest range of current ratings.

Designers often use a current shunt to measure low current being sourced out of their power supply since many of today’s power supplies do not offer adequate accuracy from their built-in measurement ...
