Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...

In electrical and electronic engineering, capacitors are fundamental components. They appear across all manner of applications, including power supplies, analogue filters, timing circuits, and energy ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Supercapacitors (SCs) generally operate at low voltages of about 2.7 V. To achieve higher operating voltages, it is necessary to build up a cascade of SC cells connected in series. Due to variations ...

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release electrical energy, helping to stabilize voltage and filter signals across a wide ...

Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit. In a simple capacitor equivalent circuit ...

Powered by a 9V battery or an optional ac wall adapter, the Model 881 handheld tester can be used to measure the equivalent series resistance (ESR) of electrolytic capacitors in or out of circuit. The ...
