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 ...

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 ...

Electrons flow through most materials more like a gas than a fluid, meaning they don’t interact much with one another. It was long hypothesized that electrons could flow like a fluid, but only recent ...
