How fast does light move in water
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. Web19 uur geleden · Asked by: Carel Lucas, Perth, Australia. Drift velocity, the average speed at which electrons travel in a conductor when subjected to an electric field, is about 1mm per second. It’s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light. The dimensions of the wire and electrical properties like ...
