It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Let us say that there are two copper wires and each wire has a point where we collect concentration of 1 coulomb. The separation of the two points is about a meter. Use Coulomb’s Law to give proof ...

Coulomb blockade is a phenomenon in which the flow of electrons through a nanostructure, such as a quantum dot or a single-electron transistor, is restricted due to the electrostatic repulsion between ...

Light-induced ultrafast electron dynamics significantly impacts the fundamental processes in nature, such as molecular bond breaking and formation, chemical reactions, and biological metabolism.

Analog Devices has created a battery monitor for primary (non-rechargeable) cells that counts coulombs and can handle a pair of output supercapacitors. Called LTC3337, “the patented infinite dynamic ...
