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

An ultrathin ferroelectric capacitor demonstrates strong electric polarization despite being just 30 nm thick including top ...

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 ...

Having acquired some piece of old electronic equipment, be it a computer, radio, or some test gear, the temptation is there to plug it in as soon as you’ve lugged it into the ‘shop. Don’t be so hasty.

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
