[@Enio856]

ElectroBOOM is too talented to be teaching in a class. Just keep making videos, I find this more informative and entertaining than a classroom.

[@roberthunter5059]

The unfortunate reality of the classroom is that you have to go into much more detail than what is done here. Engineering is all about "sweating the small stuff". That gets really tedious, whether you're teaching, learning, or doing.

Dude I think I'm learning more from electroboom than my actual 8th grade science teacher.

[@DasAntiNaziBroetchen]

Not surprising, since teachers in my experience know nothing compared to the people actually working in those fields.

[@grn1]

I've learned more from watching KZbinrs than I have from taking classes in general (including a bit of college). Some of that may come down to me being older but I've revisited some old class videos and still found the KZbinrs better at explaining shit.

[@DasAntiNaziBroetchen]

@@grn1 I guess a youtuber has to try hard so people watch their stuff. A teacher however gets paid either way.

[@grn1]

@@DasAntiNaziBroetchen That may be part of it though another part is simply the way a KZbinr can teach vs the way even a good teacher has to teach. They can't veer too far from the curriculum/have to cover certain topics in a certain amount of time, they have more of a set schedule for how long each lesson is and the lesson is usually given at hours when students may not be at their best performance (I never was). There's also forced teaching vs free learning, with KZbin we're tuning in on our time if/when we feel like it.

[@sufsanin1917]

You will learn more about this in high school.

I recently read that learning styles is bunk. I suggest an at home experiment to prove you learn well kinesthetically(spelling is for losers) too. Separate your forearms by 1 meter and have an assistant run one ampere of current through them. Give yourself time to fully experience the 10^-7 newtons of force and I bet you'll remember that factoid until the day you die. I'm so sure I'm right I won't bother suggesting how to complete the experiment in a scientifically valid way.

[@michaeljburt]

What you're asking for is not possible. There is no microscope powerful enough to "look" at electrons as they pass through a conductor. The best way I like to teach this is by saying that we only know the "average motion of a very large number of electrons". The analogy to water is pretty good, the only exception is that you literally cannot *know* the location of any particular electron at a given time. This gets into quantum physics and the uncertainty principle.

The clock at his back shows how much great effort he puts on the video (~5.5hrs for 10 min video) . Thank you :)

If one of you guys doesn't understand this, I'd suggest rewatching it. Try consulting other videos if you still don't get it. Eugene Khutoryansky has some great videos on the subject. Also Afrotechmod and Great Scott. To name a few. Don't be deterred if you don't understand something right away. Physics and electronics in general are ways of thinking that we're generally not used to. So it will take some time to gain an intuitive understanding of this stuff. But I guarantee if you keep trying you eventually will. This is a nice circuit simulator program that will help to give you a visual demonstration of various circuits. It was a great resource in helping me to understand voltage and current: sourceforge.net/projects/circuitmod/ And here's a Java version of the same program which you can run right in your browser.
