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. youtube.com/watch?v=bHIhgxav9LY Extra notes on simulation: 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?
