Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...

Building a capacitance meter is a great exercise. If you’re feeling quite safe in your digital-circuit-only life, this will push just far enough out of the comfort zone for you to see there’s nothing ...

www.quadtech.comOver the past 3-1/2 years, microprocessor current has increased by a factor of 5 and equivalent series resistance (ESR) has dropped by a factor of 7. Next-generation microprocessors ...

Hi guys, I just received an email from David Moran and he sent me his capacitor meter project with pictures and a little presentation. Here are the details and schematic. Here is the schematic of my ...
