Speed Of Electricity
The word "electricity" refers generally to the movement of electrons (or other charge carriers) through a conductor in the presence of potential and an electric field. The "speed" of this flow has multiple meanings. In everyday electronics, the signals or energy travel quickly, as electromagnetic waves, while the electrons themselves move slowly.
The word "speed", meters per second, must not be used, as many do, for the quantity of digital information transmitted per second which is a "rate", bits or bytes per second etc. This is a count of how many states of the electric signal can be sent and received in one second to carry data.
