Sorry, re-upload for extra clarification. Saves hundreds of comments over the next few years.

I would have paid double for my electrical engineering degree to have this guy explain it instead. Great to refresh and relearn things!

[discontinuity]

Hey Dave, just graduated electrical engineering with distinction and got employed, very glad I had the support of you and your content for the ride, looking at this thumbnail made me think back to the recent past where I struggled with all of this, and I'd always turn to your channel for help, thank you for doing such great work Dave

[anelson]

Really pleased to see a new fundamentals video. They're great. Looking forward to more. Thanks

[soniclab-cnc]

It doesn’t matter how many times you go over this stuff. You can always learn more and gather a better understanding of the fundamentals. I would have loved to have Dave as my instructor...

[ArcFlashWarning]

Please do more of these. We could all use the reinforcements just as footballs Vince Lombardi reinforced what a football was to his Super Bowl teams

[mikemike]

A nice blend of theory and practice, where Dave goes the extra mile (as usual!) and takes us from the whiteboard to the bench, explained in the way I think an engineer thinks. Looking forward to more.

Funny thing about that guy is his name is a real tongue twister when trying to say it in English, but actually rolls right off like buttah when saying it in French. Thanks for the explainer Dave!

[omniyambot]

I need to comment so Dave knows that these videos are useful especially for students like me. Electronics engineering for the win!

Dear Dave, You are so enthusiastic. It is infectious. I could not imagine how you could make a channel about bits of silicon so exciting. And I love the little troll with green hair sitting on the ledge of your white board/

Superb. Theory with a simple, well delivered explanation followed up with practical demonstration that reiterates the theory. Love these fundamentals vids.

[KevinNguyen]

If you thought you have seen this video before, then you did see it before! This is a reupload of the video with some extra clarification as EEVblog has said.

[bensonwr]

Remembering stuff I learned 30 years ago. I thought had long gone. Thank you!

[McTroyd]

Wow... an explanation of current and voltage sources without high-level algebra or obfuscated math constants! I love it. 👍

[twobob]

Solid, and thorough. Articulate reiteration and passionate precis. Appreciated.

Ótimo vídeo sobre alguns fundamentos da eletricidade. Abraço Dave.

Excellent intro to Thevenin & Norton

Traditionally chemical plants use 4 to 20mA values to communicate measured values from the transmitter to the controllers and then from the controllers to the valves etc. Many years ago I somehow managed to build a variable current source to generate a current signal to simulate a transmitter for use with a PLC I had on loan. I spent ages worrying about what voltage it should use. I used a 9V battery, and no smoke. The box actually got used but the company project team to check out indicator loops at site in the end. But to this day, I still don't know what the loop voltage should be.

Yes more fundamentals please. I've been learning on my own using YT videos for the last year and just signed up for the edx self study electronics course. For me, I do find it is quite easy to gloss over terms like super position and linearity but taking the time to get familiar / explicit about the basics leaves me feeling much less confused when it comes to understanding theorems, etc.
