The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron. It was ...

An ultrathin ferroelectric capacitor, designed by researchers from Japan, demonstrates strong electric polarization despite ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

A nuclear engineer busts common myths about big capacitors, explaining the real risks, safe handling, and surprising truths ...

Great Scott! A team of physicists just figured out how to make a flux capacitor. No, it’s not a real-life version of what was in the “Back to the Future” franchise (reminder: in the movies, the flux ...

Kelly has over 10 years of experience writing about home design and improvement for many prominent publications. She also spent several years working at a tech startup for an interior design game ...

While passive precharge employs a power resistor to create an RC circuit that charges the capacitor asymptotically, active precharge can employ a switching converter with a buck topology that uses ...

For semiconductor designers this outlines how a thin ferroelectric stack can retain polarization and support memory ...

Vintage electronics and capacitor replacements tend to go hand-in-hand. Why? Because electrolytic capacitors just don’t last, not the way most other components do, anyway. The metal terminal ring and ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

Combining the unique strengths of lithium batteries with crazy-fast charging, carbon ultra-capacitors could save a ton of weight and add significant range and power to electric vehicles, according to ...
