The propagation of electrons may flow that fast, but the individual electrons themselves don't. The effect of their travel is what we consider to be instantaneous.Well i always thought that a electron traveled at the speed of light thats when i went to school .
Picture a garden hose full of marbles, end to end, and you push a new one into one end of the hose. A marble will pop out of the other end of the hose instantly, but it won't be the one you pushed in.
It's the same with electrons. When you add an electron into one end of a conductor, it displaces one free electron of the 'first' copper molecule, which hops to the 'second' electron, and so on.
We consider electron flow to be instantaneous, but it's not quite. If you energized a 186,000-mile-long circuit, it would take about a second for the light to come on.
