Oh, thank you! that clarifies a lot. One more question, regarding to the electrical field propagating "at a significant fraction of the speed of light", exactly how quickly is the propagation in comparison to the speed of light.

Once you flipped the switch how quickly does the electricity reach the light bulb? I've read somewhere that it's at the speed of light but I might be wrong, I've also read somewhere that electrons flow very very slow so I can't understand how will lights will turn on instantly.
