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, ...

Medically reviewed by David Ozeri, MD An ESR test can help detect inflammation in your body by measuring how quickly red blood cells settle. An ESR test is safe and quick, with results often available ...

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 ...

An ESR test measures inflammation levels in the body. Doctors may use it and other tests to diagnose an inflammatory condition or monitor an existing condition, such as arthritis. An erythrocyte ...

Capacitor (n): a troublesome electronic component that accumulates and discharges trouble for other components. I can’t prove it, but I’ll wager that capacitors are near the tops of everyone’s ...
