“Should a person touch it?”
Almost everyone “No!”
“Wanna see it anyway”
Literally everyone “YES!”
Mom:That's curiosity
Me:They want him dead
@@cruzlouisrussell3695 I love this dark humor
False. When he asked 'should a person touch it?', everyone said yes
@@boomboxblaster8742 He meant the second time , at 1:08
Like
“Do you want to die?”
“No!”
“Do you want me to kill you?”
“Yes!”
Teach: "Should I touch 200 thousand volts?"
Class: "Yes"
Teach: "Probably Not. No."
Yes
Yes
If it were my devilish teacher who asked that question I would be happy to tell her yes
It’s actually Pikachu’s double Thunder! 😂
survey says....
"again this is not a major disappointment on my part, but why am i not dead?"

i read that comment right as he said it and it was just a weird

Hats off to this teacher, I wish there were more like him.
Do you think so
This was actually interesting and fun!
Professor: "What is a lightning rod?"
Students: "gdhjsgbdhsjkgbfhdskbghfjdkgh"
Professor: "Correct."
hahaha
WWaveform Creations You made my night xDDD
4:39 actually the correct text is
"You know what a lightning rod is?"
"gdhasdjoasdai"
"Pointed piece of metal"
He never says "Correct"
But if he said that mega, it wouldn't be as funny you buzzkill!
He never says correct.
What u r seeing is a rare species of teachers everyone wants...
True
This is why internet is better education than actual average local school lmao
every teacher i had in middleschool was like this
You can get one with paying a fortune
I’m actually watching this on a weekend
I love this guy's sense of humor.
"I'm not dead. I'm not disappointed; I'm just confused."

As an electrical engineer i can understand that how wisely you teaching and entertaining the audience.
Great work👍
Thank you!
I'm a mechanical and electrical engineer with my PE stamp. This explanation was excellent!
And why you arent excuse me,dead ?@@JeffersonLab
Students: *has been told throughout 1st to 12 grade not to touch anything in a lab*
College Professor: so I’m going to touch 200,000 volts
True

Yep yep yeep
Man, I was thinking of becoming the flash after touching that

Underated comment...
He is wearing shoes
Learnt more about electricity in 8 minutes than I have in the past 31 years what a excellent teacher!
This is the best explanation I have ever seen in my life. I loved physics but never had a teacher that 'showed' me the physical phenomenon. As a person with ADHD, I really really appreciate and love this explanation. Thank you and best of luck!
I have ADHD too and have been searching for a video to help me because I have an exam tomorrow and I’m stressed about it but this video was so great!
Try professor walter lewin's videos. 8.02.
I can't believe I just voluntarily sit through an entire 8 minutes of Physics lesson. Hats off my good Sir
Not my first time
EXACTLY
i thought i sayed here for 40 seconds
yes man
Yeah, I too.
Plot twist : electricity Is a paid actor
Plot twist plot twist the electricity is a serial killer
Plot twist: Plot twist: Plot twist: this comment is about plot twists
Plot twist:it was all a dream
TR.DEATHCRUSHER WOLF PACK plot twist the teacher is an outlet
That is. . . correct !
Absolutely super - really well-presented. Favourite moment when he gets unbelievably close to the grounding sphere with his nail! I thought OMG, if I did that, I'd probably touch!
It actually does touch. Intentionally. It's not super obvious that it does so, but you'll see it if you look for it.
@@JeffersonLab Thanks, yes, come to think of it, I think I might have spotted it. It was such a relief when I learnt that it wouldn't matter if he did touch - such a fun way of building up tension through learning! Truly a great demo!
Your students are very fortunate to have someone who can communicate such a technical topic in an easily digestible, fun manner
I would listen to this guy talk about electrons for 10 hours straight
Indeed, teacher got knowledge and skills for storytelling and keeping it entertained.
me too
nah~
Yas
I can agree I wish I would of had a teacher like this in school I might have graduated
I have a degree in electrical engineering and I can tell you...I wish school was that much fun when I was learning! This guy's a great teacher!
True, if we had more people like this we'd have more people interested in STEM fields.
Yet people insist that Voltage kills. Albeit I say it is the Ampere that kills. Sure, hig hvoltage can kill if it generates enough Ampere on impact, which it can do in a Frequency network. But DC? Nah. Without ampere, you can't hurt a fly. Therefore, high voltage isn't necessarily Dangerous in the end of the day. The Ampere is.
Is that really school
@@Helveteshit You are forgetting another very important part: Delta t.
Energy is proportional to delta t. Integral of power dt = energy. Energy is what kills. Current through the body is proportional to the power via I^2R=P. If it's only a nanosecond pulse width, probably won't hurt. Now make it one second, and you multiply total energy by one billion (assuming I=constant*[u(t)-u(t-T)] where T = pulse width). One billion (1,000,000,000x as much energy) and suddenly it's dangerous.
@@Helveteshit Also, Amperes are directly related to voltages by a very simple relationship. So the killer # of DC amperes (for example) requires some killer definitive DC voltage that is directly proportional to that # of DC amperes. If amperes kill, then the voltage required to produce that many amperes also kills to exactly the same degree. I think you may be thinking of capacity of a power source to produce a sustained current at a certain level (measured in Amperes)? Rather than just comparing voltage vs. amperes as far as which is more dangerous? V and A are mathematically related by a very simple proportional relationship in DC. Even in AC, Amps * Impedance = Volts. Impedance may vary with frequency, while resistance === impedance at DC.
I am 73 years old. I am watching this lecture, and I am learning things thank you. I had a masters degree in nursing, but they didn't cover a whole lot about electricity other than jewels. JOULS thanks this was fun.
There's clearly something good about this guy since I watched the whole video without getting bored
Or maybe theres just something wrong with someone who can't watch an 8min video without getting bored.
TheGreatSheikh I clicked on the video and was hoping to see someone comically fly across a room. I know, I'm horrible. (But IO wouldn't want to see someone die so I actually wouldn't want that to happen) But the video was very educational. I didn't know that's how currents and voltage went together.
One time I put a plug in a socket, I felt and heard a buzz, then suddenly there was a flash, small fire, and a bright blinding light out of nowhere and it all happened in about 1.5 seconds. I got up went to the bathroom, looked in the mirror, and I was covered in black stuff. I can't remember what is was called (soot maybe?). That scared the hell out of me and I am not sure if that was a close death experience or not, or if it was common, but I know that no horror movie jump scare matched that moment. lol. Has that happened to other people a lot?
Once I realized I was okay I just laughed for like 5 minutes. The whole wall within a 2-3 foot radius of that socket was also black and burnt, and that socket was no longer functional. Any idea what might have caused such an explosion? Poor wiring? Over use? Wear out overtime? That socket had been there for many 10s of years because I had that house for a while and never had that problem.
***** Thank you someone that speaks my mind
TheGreatSheikh Even better: he made about 70 kids keep attention and answering questions throughout the whole thing.
TheGreatSheikh Now if only my college professors would speak like this man does! I'd probably have an A in all my classes!
Meanwhile at every class I've ever had

This guy is such a good teacher. He literally made me enjoy sitting through an 8 minutes physics lecture. If every teacher was like this nobody would fail
A rare species of teachers which are never found on this planet hats off
He is a great teacher. He has charisma and makes learning the material a lot of fun.
blotmaster1 wish my physics teacher was like this
Aamn#2 you must be lucky af then.
My physics teacher was bored out of her mind just repeating things, not explaining. I hated that so much
Love Rush.
I wish I had a physics teacher like him my teacher gave me a detention for sneezing a lot at once I’m not even joking 😂
"I'm not dead which is a good start" Van de Graaf
You do understand that Van de Graaf is the person who invented shown generator in 1929
Lmao. Van de Graff aint the name of the prof.
The no. of likes on this comment makes things funnier, i wonder how many assumed his name to be this
@@nota5713 I’m pretty sure the person knew it’s not his name, and more or less made a joke saying that may have been what Van de graff may have said when creating the generator, just my thoughts though.
@@spongegarr6235 Given that the quote is from the presenter in this video argues against your point.
This guy was very entertaining and informative. It made me appreciate my O'level physics teachers because I got almost the same demonstration (without the comment about lightening conductors - which was a revalation) when I was 13, and remembered it all.
Well done Mr Benson in 1975
The dedication towards the concept is at a great level. Respect ❤
This guy thought me more physics in 10 minutes than my school in 10 years
I get ya
FOR REAL THO
Now that's an exaggeration
I learned 70% of my science knowleadge from internet and not school
Ok stop it's only funny of its relatable and its not
Proof that for a lot of people, the ability to learn something more complicated, becomes infinitely easier with a good teacher/instructor/professor. This guy rocks.
I literally just watched a video talking about voltages and enjoyed it because of him
Except most the kids in that class still have no idea how this is working... lol. He's a great teacher. Not everyone is a great student.
@@majorpwner241a bad teacher always blames the students
Ok he's a great teacher yes but one thing you have to note is that he is teaching the basic fun stuff. Eventually when you get into the actual details of this and you see the math behind it, it becomes boring. He is not teaching the boring part of physics, which is the math behind the scenes
@@jacobyson7629 The math is actually the most fun of physics because it says a lot about physics and its structures at fundamental level
What an amazing teacher, I forgot how fun lessons like these were
When I was a freshman in high school, my physics teacher would strap us up to one of these for certain lessons. I always volunteered. I miss that man.
Perfect example on how to teach kids something in a very good way and something they will remember for the rest of their lifes. Well done mr. Teacher
- From a colleague teacher
Indeed! I was surprised at how the kids were so engaged!
Great teacher
As an aircraft electrician, he explained basic principles of power very well. What a cool job!
Seriously, seeing videos like this make me want to go into teaching.
The science teacher we all wish we had..
We can just wish :(
Svmbah
My teachers for science(s) from grades 7-12 have all been great. It's the english teachers that I've mostly hated. There was 1 really good english teacher though. I've had a mixed bag of teachers in everything except science/chem/physics.
katze [^-^] u did? Not
Simba so true
Simba i have an awesome teacher we did this and every Christmas he blows up 2 painters cans man it is awesome
I’m a few years late but I just wanna say I’m impressed. I have ADHD so focusing is very difficult and I loose interest in this stuff quickly, I was just looking for a video to learn from for my exam tomorrow and found this video, it’s so fun to watch and I learnt! So thank you for making this interesting and fun enough for me to study with, I hope I do well!😄
Good luck with your exam!
How did it go?
That's crazy, I've been in one of these presentations in Jefferson lab when I was a kid in four or fifth grade, I didn't think I would come across again and the same guy who is presenting in the video is the same guy who gave us the presentation when I was a kid. IDK just give a bit of nostalgia. Congrats on them for getting 14 mil views on this vid and 300k subs.
7:43 _Casually explains how lightning rods work in a bonus lesson._
We need more people like this on earth.
FW911 yes sir indeed we do
These are the kind of teachers that will preserve humanity for the future...I'm so glad they still exist. My sincere thanks to teachers like you sir. You make your students better people and this world a better place.
Even though that is true. This vid is 9 yrs old😢
they always have existed what are you talking about
These Students actualy learned (not just learned for the exam and forget) more in one lesson, than most do in a whole semester.
harsha hampole good man.
Oof
Now this is called a good and entertaining teacher. I would love to have teachers like this
I went to Polytechnica in Bucharest, no one ever explained things in this manner. You literally have an experience of these phenomena directly. wow

Lol, true that tho
more like a bad one
If you glue plastic chairs to your shoes then yes....
you just need to gt a charge in the morning and walk on high heels
I learned more about electricity through this video and the responses in the comments than my whole schooling.

I had a physics teacher just like this guy. Enthusiastic, practical and is very good at explaining things in an easy way. This was the reason physics was my favorite subject at school, even though I don't really care for math and physics that much in general.

Stop it
Du dun tissss
Omg just get out
watt a good joke! 😏⚡️⚡️
Great teacher. These kinds of teachers are the only ones who can truly teach students anything, this need not be every lesson mind you. Just sprinkled in between the more "study" heavy ones to inspire the kids to WANT to learn.
this type of videos are fun to watch every once in a while

CZcams recommendations has impressed me once again. Did not think I'd sit througha an entire lesson on voltage but here I am.
"Which is an experiment we can only do once." - flew right over everyone.
Well he would've, and probably into everyone as well.
Exactly I was surprised no one laughed I did 🤣
that class seems fun... until they take the exam
Fortunately for them, this is a field trip, so there's no exam.
Jefferson Lab unfortunately for them it's a field trip, so they don't have this teacher everyday
Jefferson Lab This video is like 7 years old they are currently most likely grads by now starting college
I would enter in NASA after having a teacher like this
My name is Angelo. And I'm the forth. This is trippy
Jefferson labs class: Hey guys wanna see my this thing that has 200k volts?
My class: Ok so guys today we are gonna mix sugar and water and see the difference
I already knew all of this stuff, but watched anyway. That is what I call a talented presenter.

My high school physics teacher did his lesson on amperage and resistance vs. raw voltage by passing his hand through a Tesla coil and pretending to collapse dead behind his desk. Apparently my class was the only one that year to think of calling for help instead of just sitting there.
Every time I see or hear Tesla I think of the car first. :|
Seriously what a great teacher I hate learning about electricity cuz it confuses me for some reason, yet I also sat through this entire video learning about current and voltage the difference between the two, and the real life effects of the demonstration, bravo Mr. Teacher.
