Longtime contributor Bob Meister from Hamden, Conn., writes in response to Tom Osenkowsky’s recent contribution with respect to equivalent series resistance (ESR) and the Sencore LC-75 Z-Meter being ...

Got a bunch of questionable electrolytic caps sitting in your junk bin? Looking to recap a vintage radio chassis? Then you might need to measure the equivalent series resistance of the capacitors, in ...

Medically reviewed by David Ozeri, MD An ESR test can help detect inflammation in your body by measuring how quickly red ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

Our recent discussion about checking capacitors for equivalent series resistance continues with tips from two engineers with plenty of field experience. The first is from engineer Ed Treese. Ed writes ...

Smart Tweezers ST5S-BT is based on the popular ST-5S model of Smart Tweezers; this model offers the most features and functions as well as a basic accuracy of 0.2%. The Bluetooth enabled model can ...

A 9-V battery or an optional ac wall adapter can power the Model 881 portable in-circuit equivalent-series resistance (ESR) and dc resistance (DCR) capacitor tester ...
