The most important electronics terms, demystified in one place.

Proton

Our Take

An elementary particle with a positive charge. It’s a part of the nucleus of atoms and the attraction between the protons in the nucleus and the orbiting electrons plays a key role in how tightly bound electrons are to the atom. Despite this, the role of protons in electronics and electrical engineering is basically non-existent. Typically we let physicists and material scientists worry about them.
