* Electrons don't travel fast: Electrons, the carriers of electric current, actually move quite slowly. Their average drift velocity is often only a few millimeters per second!
* The signal travels much faster: What travels quickly is the electromagnetic wave that is created by the moving electrons. This wave, which carries the energy of the current, travels at nearly the speed of light (about 300,000 kilometers per second).
Think of it like this: Imagine a long pipe filled with marbles. If you push a marble into one end, it might take a while for that marble to reach the other end. However, the *signal* that you pushed a marble travels the length of the pipe almost instantly, causing the other marbles to move in sequence.
In summary:
* Electron drift velocity: Slow (millimeters per second)
* Speed of the electromagnetic wave: Fast (nearly the speed of light)
Important Note: The actual speed of the electromagnetic wave can be slightly slower than the speed of light in a vacuum, depending on the material the current is flowing through.
