ELEKTONS & ELEKTICITY & ELEKTRONS FOR BEGINNERS. 1. A good conductor of elekticity can be called a metal. 2. A metal is a good conductor of elekticity. 3. A metal has a thin layer of elektons on its outside surface - that is what makes it a metal. 4. Non-metals do not have a layer of elektons on their surfaces. 5. Elektons are photons that hug the surface…. 6. Whilst propagating at the speed of light in the medium touching the surface (eg air)(eg plastic insulation). 7. Elektons move in every direction on the surface of a say Cu wire - but (eventually) mainly along. 8. The propagation speed of elektons duznt depend on the kind of metal - all kinds of metals give the same speed. 9. The ruffness of the surface slows the speed of elektons - due to the extra distance up&down over the ruffness. 10. Elektons have a negative charge, equal to the charge attributed to the (silly) standard electron. 11. Elektons go straight ahead - except that their trajekt is affected by other elektons (due to repulsion). 12. Hence, after a while, elektons tend to move mainly along a wire (albeit in both directions). 13. And, elektons follow the surface. 14. If the surface of a wire duz a u-turn (eg at the blunt end of a wire) then elektons do a u-turn at the end (koz the surface duz a u-turn)(ie elektons follow the surface). 15. Elektons form a thin negatively charged outer surface layer due to repulsion from atomic elektrons. 16. Atomic elektrons are photons that orbit (hug) an atomic nucleus. 17. The outer orbital elektrons escape from the nucleus, & form an outer layer of elektons (now hugging the general surface rather than hugging individual nuclei). 18. The elektons are attracted to the positively charged nuclei. 19. Different metals will have a different degree of saturation of elektons. 20. The better conductors will have a denser saturation of elektons. 21. A battery can supply elektons at the positive terminal…. 22. And rob elektons at the negative terminal. 23. The supply etc of elektons can result in what we call voltage, or potential. 24. The supply etc of elektons can result in what we call charge. 25. A dead-end length of wire touching a positive terminal will be saturated with elektons going both ways along the wire (doing u-turns at the dead-end). 26. Elektons do not reflekt off or at a dead-end (they do a u-turn). 27. When the flow of elektons going each way is equal then their magnetic fields cancel… 28. And hence their nett magnetic field is zero (in the far field)…. 29. And there is no heat loss in the wire. 30. A dead-end length of wire touching a negative terminal will be saturated with elektons going both ways along the wire (doing u-turns at the dead-end). 31. The numbers of elektons going up & down a dead-end wire will depend on the degree of saturation. 32a. The degree of saturation will depend on the surface area available etc…. 32b. And whether the wire has a coating of insulation. 33. This saturation creates what we call resistance…. 34. Or, if u like, this resistance creates saturation (many processes are chicken'&'egg). 35. Once u have learnt the above rules then u will understand that if u somehow discharge/short/earth a length (L) of wire, then u can expect that the primary discharge will take a duration of 2L/c seconds (ie it wont take L/c seconds). 36. And the discharge voltage will be V/2 (ie it wont be the more obvious V/1) 37. And if that there wire is insulated then the duration will take 3L/c seconds (as per (6) & (32b)). Enuff for today.
Oh yea? Than what's the speed of the electrons trough a high voltage multiplier and trough the air? Question: at what voltage electrons reach the light speed trough a resistor?
I came here because I was told that electricity travels at 2/3 the speed of light through copper, this says otherwise. I wonder how much faster optical computers would be than copper.

I recently did a video on using a pulse generator to measure the velocity factor of a coaxial cable. Time domain reflectometry.

What happened? You were really on a roll with the channel before. Starting all over?
Sir please make a video on powèr amplifiers and classes of power amplifier
Oh yea? Than what's the speed of the electrons trough a high voltage multiplier and trough the air? Question: at what voltage electrons reach the light speed trough a resistor?
Hi can we increase the speed of electricity?. Could you please give me feedback. Thank you very much
Superb
Does the speed of electricity move at the speed of heat. Just wondering as they both use the same process.
