There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...

A Charged Coupled Device (CCD) is an array of capacitors, referred to as pixels, designed to store electric charge, with astronomers adopting this technology as early as 1979. When a camera shutter is ...

The capacitor is one of the most important electrical components, and we’ll learn how it works in this second part of the basic electronics course for kids. It will be explored in terms of energy ...

Engineers have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research may provide a better understanding of how to ...

Ultracapacitors, also referred to as supercapacitors, continue to make inroads into a wide range of applications, where their high power density enables them to supplement or replace batteries. Today, ...

Awhile back I was speaking to my uncle who worked at IBM fixing power supplies that they created for pcs. I asked him how dangerous it was to put your hands inside the power supply after he tests it ...

A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

A large capacitor is charged by a 6 V battery or a 15 V DC power supply. When a copper rod is shorted across the terminals of the capacitor, a large spark is produced. The spark is obviously more ...
