Speed of electricity

The speed of electricity can refer to the velocity of an electron in various circumstances, the average velocity of multiple electrons in a conductor, or the velocity of electrical signals. Electricity is usually associated with the movement of electrons, or other charge carriers, through a conductor in the presence of an electric potential difference or an electric field. In everyday electrical and electronic devices, signals (such as a pulse) travel as electromagnetic waves around the conductors typically at 50%–99% of the speed of light in vacuum. However, the electrons themselves move much more slowly (see drift velocity and Electron mobility).
