WebHow fast does electricity move through a wire? Since the velocity of propagation is very high – about 300,000 kilometers per second – the wave of an alternating or oscillating current, even of high frequency, is of considerable length. Why is the speed of electricity the same as the speed of light? WebFeb 23, 2024 · Electrons themselves move at the glorious speed of fractions of a millimeter per second. However, they are so close to each other that they are constantly bumping in to each other. This makes an electrical signal travel down a wire at somewhere usually around 2/3rds the speed of light.
