Hands down — without a doubt, one of the most universally searched topics on EC&M’s website from a historical perspective is “insulation resistance testing.” As a result, some of our most popular ...

Both analog potentiometers and digipots have output or wiper terminals that drive load resistances. How does potentiometer loading affect output linearity? How light must the loading be to achieve a ...

While almost always called "potentiometers" (which are technically defined as three-terminal variable voltage dividers), many "pots" actually end up being used as variable resistors (rheostats) ...

In a perfect world, electrical insulation would allow no current to flow through it. Unfortunately, several factors can — and will — result in the deterioration and ultimate failure of electrical ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...
