The capacitor auto-discharge module presented in this article is simply a failsafe module that automatically discharges the buffer/filter capacitor in a power supply circuit when its input supply is ...

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 ...

If a larger value of resistance were used with the same value of capacitance in the above circuit, then a smaller current would flow, therefore it would take longer for the capacitor to charge up and ...

The Leyden jar is a dissectible capacitor made of aluminum and glass that poses an interesting question of where the stored charge resides. A series of experiments can be done showing that the charge ...

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 ...

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk ...

Three packs of supercapacitors (in the blue package), consisting of six D-size cells each 18 cells total were able to provide and store the same amount of electrical energy as the smaller pack of six ...

Electric cars and laptop batteries could charge up much faster and last longer thanks to a new structure that can be used to make much better capacitors in the future. When you purchase through links ...

Find a downloadable version of this story in pdf format at the end of the story. In any industry, there are applications whose failure could mean lost revenue and increased annoyance. In very few ...
