Watch electricity hit a fork in the road
« on: December 06, 2023, 10:00:39 pm »
What is everyone's thoughts?



I see a bunch of miss statements.
And one big blaring one where he doesn't consider the impedance of the scope probe.
Still, it's thought provoking.

Sorry, not going to waste 26 minutes of my time for some dude doing self-promotion.
The crap being offered on YT is mind-boggling.

I would realy see a debunk video about this. I'm just a happy amature and for me this video looks logical...

But I have also seen a lot of spin offs of the Veritasium - How Electricity Actually Works video. And that sounds the most logical and this Alphaphoenix film goes against this - again? Or am I wrong and just dont see how there both right but look at it from two different points  ???

It certainly seems to get people's attention. Three separate threads in the same forum section here, and counting...  ;)

The probe was 10×, so10 MΩ + a handful of pF? does it really matter here? Care to explain why?

Not extremely rigorous, and with some hand waving, but still I think the results are valid, and exactly what I would expect.

Yes, that's again nothing much that you can't model with transmission lines. Nothing groundbreaking here, and the experiment, while not perfect, looks "good enough" for the purpose.
Funnily enough, in a different (but related) question, the "experiment" that Dr Lewin was showing his students and that made a lot of talk here (and elsewhere) was a lot less rigourous than that.

I'd like to see him try to explain what happens when the electricity hits these "forks in the road" :)

There are lies, damned lies, statistics - and ADC/DAC specs.
Glider pilot's aphorism: "there is no substitute for span". Retort: "There is a substitute: skill+imagination. But you can buy span".
