Electrons, as related to general electricity, are the flowing electrical current in a circuit. The ampere, or amp, is the measure of flow of electrons. One ampere flowing for one second of time passes a coulomb of charge along the wire. Electrons travel at a fairly constant speed, about 20 centimeters or 8 inches per nanosecond. They do NOT travel at the speed of light as is OFTEN incorrectly insinuated in text books.
