The components in a home audio/video system are pretty complicated to anyone without a good understanding of electronics; but wire–good, old-fashioned wire–is something we can all understand. It’s ...

The electrical resistance of a metal is caused by electrons being scattered from impurities in the material’s atomic lattice or from lattice vibrations called phonons. However, it is not affected by ...

So we know from a previous video that electricity is the flow of electrons between atoms. These electrons can move about randomly. So we use voltage to push the electrons around a circuit. And when we ...

If you think about an asylum, there are two kinds of people in it: staff and patients. We aren’t sure which one [Nick Lucid] is in the latest The Science Asylum video that tries to answer the question ...

A new type of switch sends electrons propagating in opposite directions along the same paths – without ever colliding with each other. The switch works by controlling the presence of so-called ...

Physicists have directly measured, for the first time at nanometer resolution, the fluid-like flow of electrons in graphene. The results have applications in developing new, low-resistance materials, ...

A condition long considered to be unfavorable to electrical conduction in semiconductor materials may actually be beneficial in 2D semiconductors, according to new findings by UC Santa Barbara ...

For the first time, researchers have pushed electrons to flow so fast they went supersonic, creating a shockwave. The currents of electricity flowing through our devices share a name with river ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...
