A capacitor is an electrical device that can store electrical energy. In this way it is like a battery; however, unlike a battery, a capacitor has the property of capacitance, which is the ability to store electric charge and let it out all at once,...

Both resistors and capacitors are found and used in virtually every electronic device currently made. The uses to which they are put vary from circuit to circuit; however, the functioning of a resistor or capacitor remains the same regardless of its...

A capacitor is an electrical/electronic device that can store energy in the electric field between a pair of conductors (called "plates"). The process of storing energy in the capacitor is known as "charging", and involves electric charges of equal...

Boston Scientific Corp. on Monday said it is recalling some defibrillator and pacemaker models that could fail because of an electrical flaw. The recall is the latest in a string of product problems Boston Scientific inherited when it bought Guidant...

The CEO of an electronics supply company is charged with shipping closely guarded U.S. computer technology to India for use in missiles and other weapon systems.Working with Indian government officials, Cirrus Electronics founder Parthasarathy Sudarshan ordered computer equipment from U.S. manufacturers using falsified documents about...

It's a battery that looks like a piece of paper and can be bent or twisted, trimmed with scissors or molded into any shape needed. While the battery is only a prototype a few inches square right now, the researchers at Rensselaer Polytechnic Institute who...

The chilling sounds of gunfire on the Virginia Tech campus; the hateful taunts from Saddam Hussein's execution; the racist tirade of comedian Michael Richards. Those videos, all shot with cell phone cameras and seen by millions, are just a few recent examples of the power...
