Capacitors are small devices used to store electric charges and consist of one or more pairs of conductors separated by an insulator. They’re mainly used in energy-storing devices such as televisions, ...

Back in school when being introduced to the basics of electrical engineering, we learned that the ideal capacitor was a simple, basic reactive element. It was easily modeled with capacitive reactance ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron. It was ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...

The choice of dielectric material significantly influences the performance of film capacitors in high-frequency applications, impacting energy storage density, dielectric strength, and overall ...

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 ...
