Youtube Engineering

Well, I lost interest right away when he began to try to be a college professor. If you are doing Youtube videos to explain things to a lay person, starting off by describing voltage using coulombs and joules is like describing an elephant to a blind person by describing cell wall membranes and nuclei. Pretentious babble...

<Snore>

That's kind of where I started going "hunh?".

His last response to me sounded like he was quoting a Wikipedia page for physics instead of staying on topic with basic voltage and current:

"I assure you I'm well versed in atomic and molecular orbitals..."

Yeah, that helps explain difference of potential and capacity in different wire sizes all right. He mentioned Schrodinger too...now we're into quantum wires!

I too was turned off by the beginning. Using the term 'lecture' did not seem appropriate, and his 'definition' of voltage was just plain misleading.

Shortly thereafter I quit, as I got tired of waiting for the next piece to load...

Well, I guess I was better off than any of my predecessors on this one. I tutor Elementary to High School science students, and I WAS looking for some enlightenment to help me be a better tutor. I got that by reading the first three comments, and NOT watching the video as a result!

Thanks for saving me from the drivel, folks.

When I need to explain voltage to the electrically challenged I compare it to pressure.

If they don't get it then it doesn't really matter.

I'm not sure who this perfesser's intended audience was supposed to be.

A bit shabby really.

Yep. The water and plumbing analogy works for me, also. Does get a bit sticky though when a kid asks how a sink in the line works with a complete circuit analogy.

But of course, by the time the kid gets that far, you can be pretty certain they understand the concept, so not really a bad questions, after all.

Sink would be a battery.

What would a capacitor be?

A pan sitting in the sink? But what purpose?

And the sink would only be battery if the plug was in. I understand that, but I was referring to the sink in it's normal, unplugged, it's just a piece of plumbing in the line, condition. The way it is seen and used most often.

The sink tap and drain operate as a system. A sink isn't a fluid management element until it is integrated into the system. It has properties and limitations that can be exploited.

Maybe we need to move out of the realm of basic network elements?

The sink acts as an antenna in some ways.

An air-charged bladder tank would do.

That'll do it. Blocks DC and passes AC.

This video is torture. Couldn't watch more than a minute of it. Absolutely awful. Electrons with "desire." The electron would "like" to move. "This is gonna be pretty happy to stay as it is." Gimme a break.

I cannot imagine an audience for this. Far too cluttered, complicated and misleading for people who are technically inclined. For newbies, it is absurdly abstract, while also being incredibly long, dull, uninteresting, misleading, and inaccurate, and spoken as if to a five year old.

Thankfully, my early physics teacher was much better than this... so I ended up with an interest in this stuff rather than a sense of dread.
