Why don't we use cables with cheap cores made of, for example, aluminium, with a very thin outer layer of a very good conductor like silver? If the electrons mostly move on the outside of the wire, it would increase conductivity dramatically without a big increase in price.

Electrons only move to the outside when the conductor is electrostatically charged i.e. no charge is moving. If there is a current flowing through the conductor at DC the charge density is evenly distributed. On the other hand, at AC the skin effect makes the charge density strongest on the surface of the conductor. For AC power distribution the cost-saving you describe is done for power lines.

You cleared my doubt i was having just an hour ago that a plane sheet of metal does not exert force in any direction but perpendicular...it was really helpful, btw i was searching something else but i find it intriguing to wacth it its 2:19 am and curiosity struct me thank you very much

This dude is awesome 👍😎 I hold the MS in engineering physics, though even I could get some better understanding of this concept expanding the explanation of the Gauss law))) thank you 🙏🥰 very much Keep going and explaining everything this easy and clear )) i do enjoy your content

Stuff like this is so hard to believe, because this is just straight out of an undergraduate textbook. The only benefit it has is of nice animations. People learning this stuff can usually just visualize this in their mind anyway. I would expect a high schooler to leave a comment like yours, not someone with a god damn MS in 'engineering physics.'

Why does the parallel component diminuishes? You say in the video that electrons reach an equilibrium: is it because they are moved to one tip of the conductor and due to their repulsion they reach a state of equilibrium, so the parallel component does not have any effect on electrons. Correct me if i am wrong, i didn't understand it clearly

hi Alexander, wonderful description, not found in books I wanted to have a look at your e-book material, whether its suitable for my daughter, who is finding physics a bit difficult. Can you pl share a sample chapter? to help me to decide on its purchase.

Is It correct to say that because on the conductor surface the voltage Is the same for every point, It Is equal to a equipotential surface so the field Lines of the electrostatic field of the surface charges HAS to be perpendicular to the surface itself, thus proving that the electrostatic field of a conductor Is perpendicular to the conductor itself at least locally? Good video tho, i really like your explanations. Also nice animations, good job!

The photon stimulating the electrons moving parallel to the surface shift the electron vector perpendicular to the surface initiating insulator activity on the conductor that oscillate between conductivity and insulation and as the magnetic field is sucked into the conductor the conductor becomes superconductive by the photon behaviour which initiates an interesting theory of inductsnce andcapacitsnce.

Electricfield perpendicular vector quantity but oscillate between conductor and insulator as perpendicular vector becomes a conductor aa electric field is perpendicular and in another way interacting photons produces photo electric effect that oscillate perpendicular and parallel fields shifting the metal surface as conductor or insulator accordingly and Einstein was awarded Nobel Prize for his discovery of photo electric effect.
