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, ...

In the modern age, when you hear “component tester” you probably think of one of those cheap microcontroller-based devices that can identify components and provide basic measurements on an LCD screen.

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 ...
