If you are an EE you definitely know the answer to this, or at least you think you do. If you said positive to negative, you are wrong. Then you remember that current flow is a charge of electrons ...

Key learning points Electrical charges What are free electrons? Cell polarity Conventional current direction Electrons orbit the nucleus. An atom has a neutral charge, because it contains the same ...

This article describes a new finding about the composition of bootstrap current at the edge of fusion plasmas. Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory ...

“Spintronics” is a new class of electronics where charge and spin are utilized. A pure spin current, flow of spin without charge current, is one of the important physical quantities in its field, ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies. For decades, quantum ...

One of the joys of writing for Hackaday comes in learning new things which even after a long engineering background haven’t yet come your way. So it is with the Rogowski coil, an AC current sensing ...

A research team at Osaka University is investigating an alternative method of enhancing device performance. This method involves applying a patterned metal layer, also known as a structural ...

A new silicon chip capable of manipulating the spin of a single electron could ultimately allow futuristic quantum computers to be built using conventional electronic technology, researchers say. A ...
