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, ...

A capacitor made out of the precious metal tantalum. The silver-gray tantalum beads, in the form of compacted powder, can store a lot of charge relative to their mass. This enables smaller capacitors ...

A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors. A new process for growing forests of manganese dioxide nanorods may lead ...

Many improvements in electronic miniaturization and efficiency can be tied to the development of capacitor technology, and minimizing the dielectric layer thickness has been the primary driver for ...

[Jezan] decided to introduce his son to electronics by building a small crystal radio. These crystal sets have been around for a long time, and make for a great beginner electronics project, but some ...
