Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

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 ...

Even if you remember that "charge is constant because the battery was disconnected," what you can treat as constant changes ...

Capacitors are a crucial component of any electrical circuit, and every engineer should know how they work and when to use them. But as with every electronic component, there’s a lot to understand ...

Tantalum capacitors are constructed using tantalum for at least the anode material. Capacitors in general consist of two polarized conductors separated by an insulating dielectric material. When the ...

Variable capacitors are electronic components that allow for the adjustment of capacitance within a circuit. They are designed to store and release electrical energy, with the unique feature of being ...

This article is part of The engineer’s complete guide to capacitors. If you’re unsure of what type of capacitor is best for your circuit, read How to choose the right capacitor for any application.

When Ceramic Capacitors Go Bad – Aging. Capacitor Aging applies to all Class 2 ceramic capacitors as they are built of ferroelectric materials. C0G types (Class 1) do not exhibit this aging effect, ...
