EEVblog 1439 - Analysing Veritasium's Electricity Misconceptions Video

Video Description

Dave analyses Veritasium's video "The Big Misconception About Electricity" and how energy flows in the Poynting vector in the electromagnetic field OUTSIDE the wire instead of inside the wire. https://www.youtube.com/watch?v=bHIhgxav9LY Extra notes on simulation: https://www.youtube.com/watch?v=lBycH31K-E8 00:00 - Veritasium's video "The Big Misconception About Electricity" 00:32 - Rection to the points in the video 01:11 - This is a bit MISLEADING! 02:28 - Electron drift 03:51 - Engineers use different tools and theorems 04:27 - Every electrical engineer knows this 05:17 - Everything he says is correct 08:24 - What is current? 09:30 - He doesn't address this in the video. Poynting vectors at DC 11:12 - How the lightbulb works 12:41 - At the physics level, it's correct 14:11 - My only problem with this is... 15:08 - Is it just an academic discussion? 16:17 - The undersea cable is just early transmission line theory 17:20 - So what is the answer to the question? 22:06 - What about skin effect and DC? 25:44 - Let's simulate this and answer the question 29:18 - Transient analysis 33:00 - DC Steady State analysis 34:28 - The quantitative values don't matter 38:25 - But what about DC steady state? 40:24 - What does Richard Feynman think?
