Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

The better the analog front-end for measuring battery current, the more accurately you'll be able to gauge the remaining run-time for your battery-backup system. Here's a discrete front-end design ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

I'm having problem with a starter motor on a riding mower, and need to check if the motor is getting juice and not working or if something else isn't working and no juice is getting to the starter.

HARTING has developed a component carrier that can be used directly with electronic components eliminating manual assembly and replacing flexible PCBs. Increasing precision and reducing assembly costs ...
