A capacitor is an electrical component that stores an electric charge and is used in filter circuits, since AC signals pass through while DC signals are blocked. Televisions use a large number of ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

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 ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

Capacitors are essential components in electronics, primarily used for bypassing and decoupling. Depending on the capacitor type and its application, it is prone to aging and failure. Detecting a ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

Capacitors fail. It’s what they do. Aluminum electrolytics caused my monitor power supply to fail. A failed capacitor took down Paul Rako’s air conditioner. This is a story of how two burned ...

Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...
