Using a shunt is simple. Just select a shunt resistor of a known resistance, measure the voltage drop across the shunt, and use Ohm’s law to calculate the current. Designers often use a current shunt ...

Measuring an inductor is not something that most multi-meters can do. You usually need a high precision resistor (1% or better) in series with the inductor, a function generator to put a signal ...

We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

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 ...
