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.

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 ...

Last week, we heard of an interesting Kickstarter that puts a capacitor and charging circuit in the same space as a AA battery. This is usually a very simple endeavour, but this capacitor has the same ...

Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...
