Great! Thank you so much, this explains a lot. I would have 2 questions though and I would really appreciate if you could help me out. Is the electric potential at a point in a circuit defined with respect to the field generated by surface charges at that point? And where do these surface charges come from? The battery?
The wire itself already has everything needed, metals like copper already have a lot of free electrons, all they need is a force to direct them which is here an electric field created by the battery. So, when you connect the battery, the electric field propagates through the wire from both direction negative and positive in light speed (ideally) and this force exerted by the electric field on the already existing electrons in the wire is what making the distribution of surface charges to look like that in the video. The battery itself is the reason for this force to happen, because it has some metal that has excess electron and other ion that needs an electron (a real simple look at the battery) which makes negative and positive sides, so the ion in need of an electron attract the electron from the metal that has excess electron through the circuit and that what makes voltage or electric potential difference. For the first question I don't understand exactly what you are asking for.
Great explanation

Yeah man!!.I also wanted the ans. Of above question..especially where does the surface charge came from??
