When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

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 ...

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, ...

Analog multimeters use a needle to indicate a reading along a scale. Switched-range analog multimeters are very affordable but can be difficult for beginners to read accurately, especially on ...

Digital Capacitance Meter Objective The aim of this project is to design and implement a digital capacitance meter using an Arduino Uno. The device accurately measures capacitance values and displays ...

Abstract: This work introduces portable-low-cost laboratory suite for electronics analysis and education, known as the Pro-Lab, which includes a variable power supply, function generators, multimeter, ...
