Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, ...

Look at almost any circuit, and it’s nearly sure that there will be a capacitor included in it. These two-terminal electrical components rank alongside resistors.

Capacitor discharge circuits are used extensively in fast pulse generation. In such applications, the capacitor's stray inductance (or equivalent series inductance) and series resistance play an ...

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

The Quick-Check Transformer & Capacitor Tester from HD Electric is a versatile tool for quick and easy checks of capacitors, transformers and the connections made to them. In the field, the ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

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, ...

Sample-and-hold amplifiers sample an analog voltage and hold it until an ADC can digitize it. A perfect sampling circuit holds a voltage until digitizing is complete ...

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 ...
