Web16 mrt. 2024 · While the molecules in air can be trapped in a smaller space, they don’t want to be, and they will spread apart as quickly as possible the first second they can. That’s what causes pressure. Atmospheric air has 14 PSI of pressure (1 bar) but can be forced up to 6004 PSI (414 bar) of pressure when compressed into a smaller state. The word electricity refers generally to the movement of electrons (or other charge carriers) through a conductor in the presence of a potential difference or an electric field. The speed of this flow has multiple meanings. In everyday electrical and electronic devices, the signals travel as electromagnetic waves typically at 50%–99% of the speed of light in vacuum, while the electrons themselves move much more slowly; see drift velocity and electron mobility.
